[pvrusb2] WinTV PVR USB2 picture distortion - upgrade from kernel 2.6.29.3 to 2.6.30

[Alex Kilgore]

Hi,
Recently I updated my kernel from 2.6.29.3 to 2.6.30, and my
WinTV PVR USB2 picture is now no longer correct, it has red, blue and 
green vertical lines going down it and only about half of it appears

It looks *fine* when i read from /dev/video0 with mplayer
but when I use mythtv, the picture is distorted (amd then after 
quitting, even using mplayer, it shows the same symptom) until I reload 
the pvrusb2 module, I would think that this is some sort of 
configuration error with mythtv, except for the fact that it operates 
fine when i move back to kernel 2.6.29.3

This is the output when the card is detected
