I would definitely agree with that. I suspect the aging power supply, interrupts, or some motherboard aspect was responsible. I'm leaning toward the power supply, as there was also the desktop corruption that I was experiencing independent of any vdpau hiccups. I've talked to MS-Windows users who put in graphic cards, where their PC had inadequate power to run the card, and they saw such effects under a different OS (which supports the inadequate power supply theory).
Again, my apologies for wasting the time of those trying to help on this thread.
