Hi NG,
i'am using winXP w/ ati radeon 9800 and an tv-card (pinnacle ProTV).
When i capture movies i geht small stripes, looks like distortion, only
in scences with fast motion. For example waving handes.

I use DivX or Mpeg4 for compressing the movies on the fly.

I searched several newsgroups, ati support page but i don't find any
help.
Furthermore i switch some option in the driver-preferences with no
effect.

Can anyone help?
Greeting, Jens (Germany)

It might be as simple as a low-quality cable carrying the TV video, or a
problem with the Pinnacle interface.  I would try a higher quality cable
first.

Anything only happening with fast motion should be a sign
that either the cpu (or other system parts as contributing
factors) is too slow *as configured* if not in general, or
the encoding parameters are too aggressive and/or bitrate
too low.

What "might' be happening is that you have a some sort of
"intelligent"(?) deinterlace filter running, which will tend
to do exactly that, not deinterlace the rapidly moving
portions of each frame.  Check your Divx codec settings and
those of the software doing the capture.
