I had some time to try this out tonight.  I couldn't really see much 
difference in the log notices between the LiveTV output and the recording 
in-progress ouput during playback.  There were some minor query differences 
at the beginning, but during the bulk of the playback, there wasn't really 
any difference in the messages.  It was all sound buffer and A/V sync 
messages that appeared to be very similar in both instances.

It seems like once they get playing, they're in much of the same state, but 
something else is going on.  It could be backend related, but that wouldn't 
explain the same behavior I see on a dedicated frontend.
