Display and X config
I'm using a Panasonic PT-AE500U LCD projector (1280x720@60Hz native) hooked to an nVidia GeForce 7600 GT via DVI. Relevant sections of my xorg.conf looks like this:

Problems with my config
The Fusion HDTV5 adapter doesn't seem to work well with my hardware. I see frequent pci_abort messages in /var/log/messages that result in small glitches during recording. This is apparently due to lost interrupts on the PCI bus. The problem occurs in any PCI slot on this motherboard. Underclocking the RAM and setting the PCI Bus Latency to 32 in BIOS seems to help but not eliminate the problem.
