Jim,
Tuners are DVB-S2 (2x dvbsky s952).
Probably I'm wrong, but is it possible that with g3944ca9, when new 
channel is starting to play, LiveTV chain waits for key frame in 2 
places: in recorder and in player ?
Generally #1 isn't big problem (albeit users immediately notice it).
#2 is really annoying (is also present without g3944ca9, but g3944ca9 
makes this much more frequent).
#3 & #4 are issues which forced me to revert this commit.
