Yes, v4l2-ctl -L for a list and set it with v4l2-ctl -c <control=value> v4l2-ctl -c stream_type=5 (MPEG-2 SVCD-compatible Stream) v4l2-ctl -c video_bitrate=<value> > 2) I feel the image quality is worse than under windows.

Try to set temporal_filter to 8 or 0 via v4l2-ctl. > Oh, and a 3): > Is there a TV application under Linux that can cope with ivtv? tvtime > doesn't work, KWinTV neither, AFAIK.
