Subject

Scrolling display on TV and monitor when playing the Dinosaur/Space 
Adventure using TVCoder on 50 Hz video standard.

Description

User will encounter the above mentioned problem when attempting to play the 
above games using TVCoder on 50Hz video standard.  The root of the problem 
being that there is a programming bug in the file KAV.EXE of the Dinosaur 
Adventure & Space Adventure.  When executing the program on 50Hz video 
standard, it reprograms the VGA card's register into a non-standard VGA mode 
(or "mode X") thereby changing the frequency to 60Hz.  While the TVCoder 
when set to 50Hz is expecting a 50Hz signal from the VGA card, however 
receive a 60Hz signal instead, thus causing the display to scroll vertically 
because the V-Sync is out.

Solution/Action

As this problem is due to programming bug(s) in the application, user who 
encountered such problem will have to approach the vendor (Knowledge 
Adventure Inc) for an update.
