I run a P3-1400 Tulatin (slightly more cache than normal). The machine has 4 tuner cards, 3-PVR250's and 1 Air2pc. 768MB ram, Nvidia 5600, 4 SCSI (10K, 80MB/sec) disks in software raid 0. It is able to record all 4 streams and play the HD stream at the same time (frontend/backend). CPU load runs about 70-80%. In general, it will not skip frames, but its not out of the question. Any fast forward or something will cause about 5 seconds of frame skipping while it catches up on its cache. In general, I would not recommend attempting running the HD playback on such a machine, but its what I have and it gives it a good-ole college try. Certainly don't try anything slower. Maybe soon I'll upgrade, but not just yet. My Xeon machine can play without XvMC, but even it can skip a few frames if things are not in its favor.
