Folks,

From the start, playback of DVDs on my Vibrant LS has been jumpy. Despite turning off power management and setting the resolution correctly, about 10-20 times during a typical movie, the audio and video would get out of sync and the picture would briefly halt and then jump a second later. The movies were great quality visually, watchable, but
the jumps were very annoying.

Just recently, I found the solution. From examining Sigma Designs web site (creator of the Hollywood mpeg-2 card), the latest READMEs with their drivers suggests that if you are running Windows 98, you should run 'msconfig' and turn off:

General / Advanced / Enable UDF Filesystem

The difference was very evident. I played several movies that previously caused jumps, and no jumps occurred. Also,
8x rewind and FF were now flawless, whereas before there would be "tears" in the picture--as if the screen could
not update fast enough.

The README that came with the drivers from Transmonde are from 1997, and therefore only are aimed at Win95 users, which apparently do not have this problem.

Thought this information might be useful to anyone
out there having similar problems.

If anyone out there knows why this switch impacts the
quality so much, I'd be glad to hear it. :)
