I don't remember seeing flickers with the IVTV log entries below. I
checked to see if I have any recordings from the time of this entry but
the oldest recording i have is Oct 25.

I had posted to the ivtv-users list at the begining of November which
contains the details of my set up when I first noticed the issue.
http://www.ivtvdriver.org/pipermail/ivtv-users/2005-November/000196.html
If you need help I can downgrade to a paticular firmware to see if the
issue exists.

I've been watching TV with 0.3.8 and 0x02040024 for about 2 hours now with no problem. It looks like the problem came in between 0.3.8 and 0.4.0.
