I've only done a make clean, but mine segv's with Kernel 
Deinterlacing.... Bob and None are fine and Live TV Plays OK.

It does play sometimes with the same affect as above.

Handily, I don't have a debug build, but this is the (rather useless) 
backtrace that at least shows where the segv occurred.

I'm on x86_64 by the way.

FWIW, I noticed problems with interlacing >2weeks ago, but as I am new 
to getting TV working on myth (only used it for music/movies until now) 
and only recently coming back to subversion, I wasn't sure if this was 
an old issue or me messing my compile up.
