Logic Board Reset Button
----------------------------------------------
The "Apple MPEG Media System Installation Guide" instructs the person installing the Apple MPEG Media System card to press the reset button on the logic board before sliding the logic board back into the computer case. Occasionally, after installing new hardware in your computer, the computer will not reboot until the reset button has been pressed. Pressing this button will also reset the following System 7.5 system parameters to their default values. Any of these values that you have changed from their defaults will need to be reentered after pressing the reset button.
system date and time
mouse tracking
master sound volume
double click rate
caret (insertion point) blink rate
disk cache size
menu blink
auto key threshold and rate

Limitations
----------------------------------------------
- If the computer crashes or is turned off while the Apple Video Player is open, the Apple Video Player Prefs file may become corrupted. If the computer has problems loading VideoStartup at boot, drag the Apple Video Player Prefs file to the trash and reboot.
- The MPEG hardware only supports playback of one MPEG movie at a time. Some cosmetic problems may occur if multiple MPEG movies are opened at the same time.
- The Video and Audio of MPEG files may stutter momentarily when movie time location is changed during playback by using the slider control.
- Video capture of MPEG movies is not currently supported. Future software releases will include this functionality.
- The "Sharpness" slider does not affect MPEG movies in Apple Video Player.
- Some MPEG files, such as those which are playable by the Sparkle application, are not currently supported. Future software releases will support playback of these files.
- Apple Video Player was not designed to play QuickTime movies so movies containing a mix of MPEG and QuickTime data may not play properly in Apple Video Player.
- Changes made in the Finder (adding or deleting MPEG files) are not reflected in the Apple Video Player pop-up menu unless Apple Video Player is exited and restarted.
- Apple Video Player MPEG Movie Selector pull-down menu holds a maximum of 40 movies.
- Frame forward and frame backward buttons do not control MPEG movies as smoothly and accurately as with standard QuickTime movies.
- Multisession CD-ROM drives are required for playing MPEG movies form CD-ROMs. The Apple CD SC, CD SC+ and PowerCD are not multi-session drives and do not support MPEG.
- Some CD-i movies may not support chapter navigation.
