Yes, but in my casem there is something even more wrong than that. The 
X background is _way_ to big, and even once mythTV comes up it's still 
something like 10 to 20 pervent larger than the TV can display. And it's 
fuzzy to the point of not being readable.

Also, if I just load the saa7172 module, and check the "Use PVR-350 out",
I get a very nice looking display of the show I'n watching (albeint I
can't seem to gracefully exit the playback :-(). But if I load the ivtv-fbi
module, and change the X vonfig file so the X session is on the TV, then
plyaback (with PVR-350 out enabled, _or not_ , I get a very poor quality
picture.

I'm suspecting that the problme lies in my Xconfig file.
