Yes, it seems to happen right after starting the stream dump when the HD spins up, or if I switch virtual desktops or scroll around the virtual screen. Maybe that explains why I always get weird A / V sync issues. or mplayer's fault. bleh.

Not using SATA here. procinfo shows: irq 0: 327576176 timer irq 16: 22981007 eth0, mga@PCI:1:0:0 irq 1: 264741 i8042 irq 17: 2885663 bttv0, bt878 irq 8: 11302046 rtc irq 18: 2395942 bttv1, bt878 irq 9: 0 acpi irq 19: 410297 Ensoniq AudioPCI irq 14: 24775224 ide0 irq 21: 4050071 uhci_hcd, uhci_hcd, irq 15: 721948 ide1 I do have an analog card (irq == 18) in there aswell. > There was no solution except to replace the card with one that used a > better chipset. That's weird. it worked without problem while using the machine interactively on my old dual celeron. maybe the system distributed IRQs between the CPUs and did not hammer the system as much as a single CPU system. Now to wait for dual core processors to solve this problem, heh. > The Lite card is cheaper than the FusionHDTV non-Lite because the > chipset is crap for digital TV. Sorry about that. Pity most "reviews" mention there are practically no differences between cards besides the windows software. Now I kind of regret getting the Lite version. Looks like this chipset is the realtek version of tv cards. heh. -David.
