Re: Digital cable box and audio sync problem

I've noticed that lip-sync is off if I run my monitor at a resolution higher than 640 x 480 and play MyTV in Full Screen mode.

Depending on the speed of your system and the graphics accelerator (built-in or 3rd party) you may notice lip-sync being off. This has to due with non-linear video scaling. The best way to insure accurate lip-sync is to play MyTV so the graphics accelerator isn't asked to perform non-linear interpolation. To do this, play MyTV at ½, Normal or Double resolution; and if playing Full Screen, by setting your desktop resolution to 640x480.

How do I set my system to get the best frame rate and lip-sync performance?

1. Turn Virtual memory off.
2. Turn File Sharing off.
3. Turn Apple Talk off.
4. Run in Thousands color mode.
5. Play TV in one of the preset window sizes (1/2, Normal or Double); or if playing Full Screen - set your desktop resolution to 640x48.
6. If your system has advance settings in the Energy Saver Control Panel, make sure "Allow process cycling" check box is NOT check.
dunno if any of that is relevant for you?

to Cable Forum, btw
