At the end of the month I'll be getting a DTC-62xx (I think) from RCN here in Boston. I'd like to capture via the Firewire port and watch it on my TV, but I understand that the XBox probably doesn't have the horsepower to decode and display a 1080i signal. Is there a video card with component video outputs that I can drop into the 4x AGP slot on my mobo that will be able to render a 1080i video stream?
I've heard people mention that some Nvidia 6200-based cards come with a component-out dongle and they work well for HD video, but all the cards I've seen say AGP 8x (or PCI-e). Would an AGP 8x Nvidia 6200 card even work in a 4x AGP slot, or would the video kinda suck if the card stepped itself down to AGP 4x?

ATI's drivers don't support XvMC. Rumor has it they're "working on it"
(and have been for literally years). So, go with NVIDIA on the frontend.
Also, take Fred's advice--the frontend needs to be the more powerful
system (especially if doing HDTV). If you're using hardware encoders
for SDTV (i.e. Hauppauge PVR-x50's) or digital video capture cards (i.e.
DVB or ATSC (US HDTV)), the backend just has to dump data to disk. The
commflagging and transcoding are the most processor-intensive parts on
the backend but don't have to be done in real-time. Also, you can have
your other Myth machine (that you use as the frontend) do some/all of
the commflagging/transcoding.
Also, my dedicated backend has a 2MB PCI graphics card in it. I may go
up to a spare MX440 just so I can use the AGP port and free up a PCI
slot (stupid doesn't-support-AGP-1X motherboard won't let me use my Riva
TNT 8MB). A 9550 is a bit of a waste of a video card on a backend, so
if you have a cheaper card that fits the board, you can save the 9550
for a different system. (I don't even start X on my backend.)
