[mythtv] A/V diverged by +/-30 frames, extending frame to keep audio in sync

[Christian Hack]

Isaac,

Did you ever look at that problem with that file you downloaded from me? I
have another here with a similar fault if you want it. Using mythfrontend -v
playback I get logs like below. Audio starts to break up just after the "A/V
diverged lines". Interestingly it happens about the exact the show started.
It's also one of the shows I had trouble with previously.

NB: I'm currently using the 0.18.1 rpms
