[mythtv-users] Prebuffering pause on FF and or Rewind?

[Brian L. Walter]

Greetings,

Recently, I've noticed that we can't reliable fast forward or rewind, 
getting the infamous prebuffering pause.

I've got a gigabit network between the frontend and backend, and the 
throughput seems reasonable (around 800 mbits), the backend is very 
lightly loaded, nothing going on it (just recordings, but, the load is 
*low* as is the cpu usage).

Could this possibly be a bottle neck at the disk level?  I'm using SATA 
drives, which, apparently, you can't turn dma directly on for, though 
there is mention in the logs about using UDMA/133...

TIA
Brian
