Hi!
Yes, indeed! The patch solved the problem. Now I can use Teletext again
while watching TV ;-)
Thanks a lot for the great support!
Best regards!

Fixed! It's a driver bug. The VBI DMA is handled in a special way and is
marked with a bit. However, that bit was set at the wrong time and
could be cleared by mistake if a PCM DMA request would arrive before
the VBI DMA was completed.
This bug is not specific to PCM, but the different timing of YUV+VBI or
MPG+VBI probably prevents this bug from occuring.
Still, it is a rather serious bug and it warrants a ivtv-0.10.5 release.
I'll see if I can get it queued for a 2.6.22 dot release as well.
Please report back if this solved your problem completely.
Thanks,
Hans
