What exactly is Xv? Is that something that MythTV depends on?
Yes. Xv is the X11 extension that enables 2D scaling of video to be done by your video card hardware. Without it, your CPU must shoulder the load. If you're recording at, say, 640x480, but your display resolution is 800x600, then to display full-screen the video must be scaled. Doing the scaling in software is quite taxing on your CPU, hence the need for Xv, so you can let your video card do it. Without Xv, I doubt you'll be able to watch LiveTV on a PII-400 or whatever it is you have. That's a pretty lightweight box to try and serve as a combined backend/frontend IMHO, even *with* Xv.

I had to turn-off XvMC because it was causing myth to error out. I'd
like to enable and use it (I think), but not sure how to about it. Also, didn't I see somewhere that some of the de-interlacing routines
require XvMC to be disabled?
Xv != XvMC.
Xv is hardware-accelerated 2D scaling.
XvMC is "X-Video Motion Compensation", or in layman's terms, hardware-assisted MPEG-1/2 decoding.
