OK, I got my new kernel built, booted, and all that jazz.

Using 2.6.15.1, with bttv and btaudio based on some archives suggesting 
btaudio over alsa bt87xx.

I no longer get a segfault, but I still don't get a clear image on the 
remote.

Specifically:

First time around, the frontend connects, and gets a green screen with a 
horizontal fuzzy bar across the top, exactly as if there is no signal or 
wrong standard/frequency.

After 15 seconds, the display freezes, and the frontend displays an 
error about 'something went wrong' or similar.

After that the frontend can no longer connect to the backend when I 
click on Watch TV.

The logs for the backend are attached.  Basically it is getting no 
signal from the card.  I can bring up xawtv and pull in channel 28 fine.

The frontend and the backend are talking since I can pass channel 
information to the backend from the frontend, and I get a video image....

Any suggestions?  Is it possible to turn on greater debugging so I can 
what standard/freq MythTV is setting the card for?  Is it possible the 
frontend is setting a different standard from the backend?
