I'm trying to capture YUV data from /dev/yuv0 at
720x576. Picture is ok (using patched mplayer) but it
stops after 1-3 seconds using mplayer as well with cat
/dev/yuv0 > file.yuv. System does not freeze, it is
possible to stop application using C-c. I tried to
increase yuv_buffers to 256 but with no difference.
When decreasing the resolution e.g. to 720x384 the
capture time increases by another 1-2 secs. The system
should be fast enough - Athlon 2000+. ivtv driver CVS
sources were downloaded on 27.08.2003.

Here is the log:
