No the dd stuff is to /dev/video16 which is the mpeg
playback not the frame buffer.
The problem is probably that its lost its pal setting.

I would check that you have the std=2(I think and this
is from memory since i'm at work) option to force PAL
mode for ivtv and then reload ivtv as well as saa7127.
