Are you sure that it's not just the interlacing problem of "standard" 
tv-transmissions? (e.g. the NTV-news ticker is horrible, in opposite watch 
some recent movie's as they are typically transmitted in full-frame mode, 
they should be clear.)

I've observed the same with old S3-968, then with Mach64 and now with 
Voodoo3000 - always thought it's just the interlacing as i have it with Bt878 
too (and it's nothing special to fullscreen-mode, you can just see it better 
then).

If your graphics card has a TVout, so that you can display the monitor image 
at a TVset you will probably not see the stripes where at the same time they 
are visible at your monitor because a TVset has long not that sharp an image.

It's really a pity that DVB is not used to it's full performance, aka HDTV 
and multiple audio-pid's for any movie :-(
