Merc, the destination is really low res...I don't think any 1080i content will ever be displayed. 720P content played just fine. Thanks for the tip on DriveSpeed.
udaman, thanks for the tip on that motherboard. It looks promising, except for the manufacturer (IIRC, the budget branch of ASUS).
Here are the parts currently in this build (from my spare parts bin)
Silverstone HTPC Case
Intel C2D 2Ghz
1GB DDR2 800Mhz
WinTV-PVR250
Fujitsu 80GB 2.5" SATA HDD (7200RPM)
Samsung SH-S183 SATA DVD-RW
Seasonic S12-330W
Connected via network: 2TB Buffalo TeraStation
This machine is going into a component stack that is already in a wooden cabinet with an insulated door (vented out the back).
