[mythtv-users] Choppy HDTV playback

OK, I have recording happening!
Thank you everyone!
I am running 0.20-fixes, and it all seems to be working.
I can record on both tuners, and play back - almost. (Aside: the
backend has 4-400GB Seagate SATA drives, and those things are *NOISY*!!!
Definitely not recommended for a frontend; with both tuners recording,
it sounds like someone is rolling a tin can full of steel balls inside.)
Typically I transcode the HDTV recordings down to 720x480 so my other
frontends can handle them, but I have two front ends that should be able
to handle the full resolution stream.
When I try to play them, though, I get very choppy playback - two
seconds of play, pause, two seconds of playback, pause....
This is also the case with LiveTV.

which indicates that the frontend (poseidon) is restarting the transfer
every two seconds....
Is that right? Where do I look? Backend should be adequate - it barely
breaks a sweat. Poseidon (the frontend) is an Athlon 2800+ with an
Nvidia 6200 and DVI out to a 1366x720 LCD panel. Not enough horsepower
there?
