Indeed,
xine -D stdin://mpeg2 < /dev/video0
fixes the problem, when viewing from the VHS.
I know nothing about interlacing - how can it be that among the movies from the
same tape, recorded on the same TV channel, not all display the problem?
Or maybe it's just that it's more visible on cartoons than on movies.
If I always enable deinterlacing, can it create trouble with other recordings?
And now the real question is: how do I enable deinterlacing when recording from
/dev/video0?
ivtvctl --set-yuv-mode={0,1,2} doesn't seem to make any difference.
Many thanks for your help,
