As I said before, I'm using a single 250GB SATA disk on this machine.
I haven't done any kind of tuning of it. The numbers you list are
similar to what I'm getting. My point was that even though the 'remaining'
disk throughput drops dramatically, it still is enough to play another
show on another machine (serving the file over SMB, as I don't have
another frontend). I'm not sure why playback on your machine would start
stuttering badly. Maybe using XvMC gives me a little extra 'oomph', or
maybe sharing over SMB is more efficient than having the backend serve
up another stream.
