[mythtv] capture problems

[Andrew Mahone]

For reference, I have some images:
http://user.pa.net/~dbblm/good.png
http://user.pa.net/~dbblm/bad.png

The good image is on frame before the bad one.  The rest of the recording 
resembles the bad image, making it pretty much unwatchable. I first noticed 
in a recording from Wednesday night, these frame are from one Monday morning.  
I can also get it to happen in livetv by changing channels a few times, and 
it has (a few times) started spontaneously after starting live tv, as it did 
in the recordings.  I can trigger it with no filters, with both ffmpeg and 
RTjpeg encoders.  I can't reproduce it with tvtime, so I don't *think* it's a 
v4l drive issue, although that's possible (I update my kernel about a week 
ago).  I've already tried rebuilding with more conservative CFLAGS, which 
doesn't seem to fix it.  I'll try building a few older revisions to see if I 
can find one that doesn't do it.  Can anybody else using software capture and 
recent CVS MythTV reproduce this?
