Thanks. I've tried with powertweak, but it doesn't help. Later I've compiled a
2.6.3 kernel, where it was OK even with UDMA4, but freezed with UDMA5. Now
for some reason that kernel is not loading my sound modules and has other
problems, so I gave up and running with UDMA3.

Now about QtVision (as I started to use it): in v4l (/dev/video) mode I don't
have overlay, so the application consumes about 3-6 % of my CPU (Athlon
XP2000+) and sometimes I even see "frame skipping" effects. But in XVideo
mode the image quality is worser. Is this known and is there a fix planned
for it? In the old kwintv there is no such problem.
