I'm having trouble getting XvMC playing outside of MythTV but I'm
managing to watch a sample 1080i clip with an AthlonXP2000+ without
needing XvMC, so yours shouldn't have any trouble.

At a guess from the logs you gave the mpeg stream could be corrupt. Is
dma on for your hard-drive? 

#hdparm -d /dev/hda

(Change hda for whichever drive you're recording to)
