No problem for SD but will have trouble decoding HD without Xvmc.

Mythtv will work with less than 512 MB RAM but I'd recommend 512 as the minimum.

Same as above -- will be fine for SD but underpowered for HD. It may
work with Xvmc but I'm not sure.

Double that and you should be fine.

You'll save yourself some time and some hair if you use an
nvidia-based card. FX5x00 or 6x00 series cards are golden and cheap.
Plus, only nvidia cards currently support Xvmc (which uses the gfx
card rather than CPU for video decoding).

Not sure if this card is supported but even if it is I assume it's a
framegrabber, meaning the CPU needs to do all the heavy lifting.
You'll be doing yourself a favor if you use a hardware encoding card
instead, eg a Hauppage 150/250/500, for SD. For HD have a look at the
HDHomerun -- it's external so it saves you a precious PCI slot, and it
supports two inputs.

With some work and some luck you could get a functioning SD-only
system on this platform but I wouldn't recommend it considering the
other gear you have. It would only work if you were only running
processes necessary to Mythtv, and were using a hardware encoding
card. Even then menu operations would be sluggish, com flagging and
transcoding would take forever, and the whole machine would just feel
muddy and unresponsive.
