I'm getting one of these as soon as I have a spare $200... :)

How do you think an Athlon XP 1700 w/512MB of RAM and a GeForce 4 MX
440 would handle playback? I may also have to switch in my spare
GeForce 4 Ti 4400, so I can go DVI to Component video, speaking of
which, where is the best place to get a converter that'll let me feed
my HDTV's component video input from my video card (I'm just using
S-Video right now, which is fine until I go HD... :). I've found one
(linked below), but prices vary all over the board w/DVI cables...
Oh yeah, and the guy at Magnolia Hi-Fi (local audio/video phile shop)
insisted it is impossible to output from my computer to the TV via DVI
to component. I assume this would do the job though:

Yep.

Not sure what you mean by that. I don't have any performance issues,
but then I don't have an HDTV tuner card yet either.

Like I said, as soon as I can afford one...
