Via CPU's are slow. They do, however, have hardware decoding for
the mpg stream.
I use a PVR350 + EPIA MII without many problems; if you go this route
make sure you flash the latest beta bios from VIA to solve DMA issues.
If you just wanted a hardware encoder (PVR250 or similar) that works
too, although I am told the 350's output is superior to using the
unichrome drivers for the onboard decoder.
I believe newer VIA's will do mpeg4 as well, but the MII only does
mpeg2. Go peek at via's site ;)
For what its worth Im currently using a Zalman northbridge heatsink
and a big, but slow, case fan on my board to reduce noise and its
very stable. If you were going to drive the CPU more, it might not
be such a good idea, although VIA do ship lower speed passively
cooled EPIAs as well. Mines an M10k.

I'm not using my epia to run DVD's, but I have used it to play divx and
mpeg streams using mplayer (rather than the pvr350 hardware), and they
play back just fine. I'm PAL as well.
