Some more information in case it helps.  I dmesged to see what was going 
on at the kernel level, and this is what happens when I run the backend:

saa7115[0]: decoder set norm NTSC
saa7115[0]: set audio 0x02

Then, when I try to watch live tv, mythfrontend locks up on a black 
screen.  I switch to the console and check the backend, and predictably, 
it gives me:

Unknown video codec: VIDIOCGCAP :: Inappropriate ioctl for device

dmesg then shows:

ivtv: ivtv-api.c: unknown ioctl 0x803c7601

It looks like mythtv is trying to set the card to a mode that doesn't 
exist.  This is weird.  If anyone has anything to add that could help, 
or a solution, I would be very grateful if you could help me out.  I 
hope I get this fixed soon.  This really sucks :(
