Working
with Software MPEG decoders (codecs)
![]()
Microprocessor
requirements

How fast
does my computer need to be to run software MPEG instead of running it with
an MPEG card?
Theres
two answers here. The answer depends on whether youre using standard
bitrate courses (typical cd-rom rates) or low bitrate courses.
If youre playing
low bitrate course files, a 386/33 or faster computer
will work fine for 128Kb files. A 486/25 or faster computer will work fine
for the 256Kb files.
As for standard bitrate
files, some MPEG software decoders work with 486/66 computers with a very
fast video card. But the playback performance is usually very poor . We recommend
that you have at least a 133MHz Pentium with a accelerated graphics card
that has DirectDraw drivers.
Making
it work
![]()
Im
running a software MPEG decoder. Its not working. How do I get it to
work?
The first step
to isolate a problem with any MPEG device driver is to get it to run with
the Windows MediaPlayer. If it works there, using its MCI drivers, then it
should work with our software. If you cannot get MPEG files, both
files with .mpg and .mpa file name extensions, to play in MediaPlayer, then
you do not have the MPEG card, its drivers, or your software driver properly
installed. Check with your supplier of the MPEG card or software driver.
With all that said, there are times when we have trouble with some cards
and software players. Not all MPEG decoding drivers (software and hardware)
handle MPEG audio and video files the same way. We have programmed work
arounds for the problems we have encountered in our tests of MPEG software
and hardware drivers. See the section here on Working
with the Advanced Options in Training Manager

Improving
picture quality
![]()
Im
running [any software MPEG player] with the standard bitrate (cd-rom) courses,
and the picture quality is not as good as I expected. The motion isnt
very smooth and I can see the dithering (pattern of a screen or mesh) of
the colors in the picture. I know Ive seen better picture quality from
other computers that are the same speed as mine. How can I check to see if
Im getting the best picture possible from my system?
You need to
make sure you have DirectDraw drivers installed for your video card and check
your display settings for optimal screen resolution and adequate color
depth.
Most video cards include a driver diskette that contains DirectX or DirectDraw
drivers for it. DirectDraw is a component of DirectX. If you do not have
your cards driver diskette, you can download and install DirectX free
from Microsofts website
(www.microsoft.com), a generic DirectDraw
driver is included. Installing the DirectDraw driver will allow your software
MPEG player to make maximum use of your video card.
Your display settings also play an important role in delivering good video
quality. However, you may have to experiment a little to find the setting
thats best for your system. Most video cards will give the best MPEG
playback results if they are set for 640 X 480 resolution with 16 bit color,
others may work best when set at 640 X 480 resolution with 24 bit color.
By the way, this advice also applies to the low
bitrate courses.
Most people think that the processor speed is the biggest factor in MPEG
video playback quality. Not necessarily so. The speed of your video card
is usually the biggest factor in video playback quality. If you have at least
a 133MHz Pentium processor and cant get the video to playback smoothly,
try a new video card that is faster. Its a cheaper solution than a
new PC.
If you have a machine that is very slow (processor or video card is slow),
you may have to switch into quarter-screen mode to play acceptable video.
Go into the General Folder of Training Manager and change the Digital
Video option to Quarter-Screen.

MPEG
video smaller than full-screen
![]()
The MPEG
video and course screens only cover a portion of my screen. The course
screens are displayed in the upper left corner. I have the Digital
Video option set to Full-Screen in the General Folder of
Training Manager but that doesnt fix it. Whats wrong?
Its your
screen resolution. You have your screen display set to a resolution greater
than 640 X 480. Go into your display settings control and select 640 X 480
as the display resolution. The graphics and MPEG videos will now be
full-screen.
To change your monitors screen display dimensions (resolution) in Windows
95/98/NT follow this procedure:

Im
running WindowsNT and SoftPEG. I cant get SoftPEG to work. Can you
make it work?
Nope.
Your only choice is to scrap SoftPEG and load ActiveMovie instead. You can
download ActiveMovie here.
New
installation, Training Manager not in Start Programs menu
![]()
I just installed
the first Mastery course to my system. Im running WindowsNT. I looked
in the Training Administration program group of the Start Programs menu for
Training Manager, but its not there. What happened? Where is Training
Manager?
Its on
your system. The Runtime version of the first course you installed must have
been among the two or three releases of the Runtime that failed to create
Program Items for Training Manager and Install Mastery Products in the Training
Administration program group of NT desktops.
This problem is easily remedied. Heres the procedure:
Repeat this same procedure to place the Program Item "Install Mastery Products" in the Training Administration Program Group. Link this item to the LOAD.EXE program in the \VIDEO directory.

Archiving
and purging old learner records
![]()
My database
files are getting very large and I want to purge the records from prior years,
but I still want to save the old records in case I need them again. Oh yeah,
and I dont want to have to enroll everyone again. ...One more thing,
I dont want to lose the records for training that weve already
done during this new year.
How can I do that?
No problem.
The procedure is safe and short, but its still is a little too long
for this page. Click here to get the step-by-step

How do I
convert my old DOS learner records to the new Windows database structure?
From the DOS
prompt, heres the procedure:
If you deliberately or
inadvertently run the DOS version of the Runtime after the learner files
have been converted, the additional DOS records can be appended (added) to
the Windows learner database by repeating the three steps above.
Repairing
DOS Learner Record errors

The system
reports errors in my DOS learner records. How do I repair
them?
If one or more
learner records (DOS system only) exhibit errors, such as during the conversion
of DOS to WINDOWS (gen2to4.exe) run the following diagnostic program to repair
all possible files.
Here are some common error messages you might see, along with the appropriate code used to repair the file. These examples refer to S1 which represents the student number assigned to each record. Use this number when the system prompts you to enter the <learner #>.

Audio
cuts out early
![]()
Sometimes
(especially on quiz questions) the sound stops before the narrator finishes
a sentence. Why? Can I fix it?
Its an
error in the MPEG audio decoder (player). Some versions of older software
players miscalculate the end of the MPEG audio file and end the playback
prematurely for audio-only MPEG files (.MPA files). If the latest version
of your MPEG player does not solve the problem heres what to
do:
Buttons
on the Control Bar get scrambled
![]()
The buttons on the Control
Bar sometimes get messed up when a lesson is playing. How do I fix it?
This problem
occurs with some video graphics adapters. The problem is a bug in the VGA
driver. This problem only seems to occur with certain models of
ATI cards when your display is set to a color depth greater than
16-bit (e.g. 24-bit or 32-bit). We can not work around this problem in the
software. But you can. Set your display to a 16-bit color depth.
Garbled
(distorted) audio
![]()
When I play the Spanish
version of my course the sound is garbled. It sounds fine for the English
version. Can it be fixed?
You may experience
this problem if your .WAV output volume is set too high, or you have a bad
driver for your sound card.
This is a known problem with Creative Labs Vibra-16 cards.
Set the gain or volume control on your sound control panel to a lower value
(down to 1 for the Creative Labs Vibra-16 card). If that
doesnt correct the problem, download the newest driver for your sound
card from the manufacturers website. If youre using a Creative
Labs Soundblaster card, go to
www.soundblaster.com for your
driver.
Asks for
CD to be inserted but CD is already in the drive
![]()
The system keeps telling
me to insert the CD-ROM for a course but the CD-ROM is already in the drive!
Its label side up. The drive looks and sounds normal. Windows file
manager even displays the contents of the CD. What am I missing?
Check the Training
Manager program. Look in the General Folder. Is the entry for
CD-ROM Drive correct? Probably not. Correcting this entry should
solve your problem.
Course
screen displays in upper left portion of screen, does not fill the
screen
![]()
The course
displays in a rectangular area in the upper left corner of my Windows desktop.
It does not fill my screen. I want full-screen video. How do
I make the picture fill the screen?
You need to
put your display in 640x480 screen resolution. Your display is in a higher
resolution, like 800x600 or 1024x768 which makes all items displayed on your
screen look smaller.

Error
message: RT-302 Error [259] opening MCI file
![]()
I have a
REALmagic card and Im running under Windows95. When I try to run the
course, I get this error message:
MMSYSTEM 259. The command parameter used is not defined in MCI command set.
Popup parent alias MOV.
What is it? How do I fix it?
Its an
error in the REALmagic installation program when used on a system with OEM
release 2.0 of Windows95. Somehow the REALmagic installation program renames
the digitalvideo.mci file to digitalv.mci. The fix
is simple. Rename the file. Heres how:
Video
locks up (freezes)
![]()
Im
running the course from the hard drive (versus from the CD-ROM) with Windows95
and the video freezes in the middle of a video file. The lockup seems to
be in the same place in the same file every time.
The video plays fine from the CD-ROM. Whats wrong?
The most likely
video lock up problem is a hardware conflict. First look in the Device Manager
to look for an ! next to a devices icon. If you see one,
theres a problem which is most often an interrupt (IRQ).
The second most likely cause is using multiple hard drives that are not using
the same disk formatting scheme (FAT16 or FAT32) for both drives. NEVER MIX
FORMATS! Check for this condition by looking under My Computer
and right click on the drive, then select Properties. For FAT16
drives it will show FAT. For FAT32 drives it will show
FAT32.
