[mythtv-users] Choppy HDTV playback

[Yan Seiner]

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.

My logs on the backend show

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?
