What i recall is when DEBUG is set in local_conf.py some extra
informational ioctl is called. This bug is there for a year or maybe
more :-). User can workaround this by disabling DEBUG or removing (if
DEBUG: v.print_settings()) in ivtv_record.py as Rob already pointed
out or apply the following oneliner patch provided by Duncan Web back
in september and not the one he mentioned earlier in this thread ;-)

But if a my hijack this post, when using Duncan's his vbi2srt i
noticed something has changed since at least ivtv 0.4.0 in the auto
load process and initialisation of the ivtv card. It sets my card in
PAL settings but other specific PAL settings like framerate and
framespergop aren't correctly set. Didn't noticed this before but at
least since ivtv 0.4.0 it sets framerate=0 where it should be
framerate=1 (0=30 frames NTSC and 1=25 frames PAL). No worries still
because when recording with freevo ioctls are passed on to ivtv with
the values given in TV_IVTV_OPTIONS where i have 'framerate' : 1
and 'framespergop' : 15,
But these particular values aren't set by freevo's ioctl's ? Other
values in TV_IVTV_OPTIONS are correctly set. Did looked at the code in
V4l2.py but changes and debugging this didn't looked trivial to me.
Oh and @ Duncan this framerate issue is not the reason why the subtitles
aren't in sync with xine. There are sync probs with or without a
correct framerate or gop setting. Mplayer OTOH works fine and keeps the
subtitles perfectly in sync.
