[mythtv-users] Live TV judder until channel change

I ran through the bisect again with the same result.  I started at a
different "bad" location to try and change things up.  Same result as
previously.  Again, there was one bisect that the behavior was a bit
different.  It started out with juddery video but after about 10 second it
would correct itself.  I counted this as "bad" because in the "good" cases
it was smooth from the start.

What am I missing here on the bisect?  Here is the log from the last run:

myth at htpc ~/src/myth-dev/mythtv-0.27-bisect $ git bisect log
git bisect start

Any suggestions on how to figure this out?

Thanks!
