[mythtv] 0.11 + BTTV bug...

[Reza Naima]

I recently upgrade to 0.11 and noticed some very strange behaviour.  If
I try to adjust the contrast settings, it displays a value of 0 which
does not update -- and after not too long, the screen goes blank and
live tv stops.   At this point, even xawtv only displays a black
picture.  If I 'rmmod bttv', and then try either xawtv or mythtv, then
it works again.  

I'm going to try to do some more snooping, but I'm not exactly sure
where to begin.

Any thoughts?
