You might try a minor adjustment to your modules.conf file. This tweak 
has fixed a few video issues for others, and is more in line with the 
ivtv developer's recommendation for modules.conf. I'm not certain if it 
will help your particular issue or not, but please give it a try. 
Anyhow, change the add below and add above ivtv lines to match:

add below ivtv msp3400 saa7115 tuner
add above ivtv lirc_dev lirc_i2c

This is in the very latest rev of the doc, which I don't think Mark has 
had a chance to post up on PVRHW just yet.

The odd thing on this one is that I see pretty much identical video 
performance with this new version and the old version (I don't have any 
problems at all), while others have seen significant improvements with 
the new version.
