Mine's a straight Mandrake 9.1 install. Kernel is 2.4.21-0.13mdk.
The whole install was done according to the myth docs last July
and has never been touched. I honestly can't tell you what I'm
doing right, since I haven't really done anything. It does seem
that playback is very efficient with the nVidia drivers. My
PII-450 remote frontend with an old Voodoo Banshee card uses four times
the CPU. I guess some of that is network processing overhead. My
backend process might hit 60-70% but my frontend uses less than 15.
