following this thread with interest, I don't think the clues help an
issue I've had lately.
I have two frontends, one is my main HD frontend, with a Athlon64
3200+ (o/c'd) and 1GB of RAM and the other is an AthlonXP 1600+ (in
the bedroom) with 512MB of RAM (with XvMC enabled for HDTV). The watch
recordings screen is *slow* on the Athlon64, like a few seconds delay
between pressing up/down and it actually moving. The AthlonXP is fine
its speed in moving through the shows. None of the preview/image
settings change this behavior on either system.
Both systems are on the same 100bT network.
anyone have any ideas?
