Yeah, looks like these cables need sync-on-green which apparently nvidia
cards do not provide.  So that's a no-go.

The pickings get mighty slim when you're looking for an nvidia card that (in
order of priority) fits in a low profile case, has component output, is
fanless and supports XvMC.

I may give up on the last two items and try this one ...

The XvMC isn't necessary for me at the moment, I'd prefer not to use it at
all, but I thought when I upgraded to HD I could use it on the frontend
until I beefed up the CPU there.
