[CentOS] MythTV on Centos 4

I'm starting a project to build a MythTV box for my living room. Anyone else 
currently working with MythTV on CentOS 4?

Here are some of the gotcha's I've worked through so far:

- I was originally planning on using KnoppMyth. But their CD appears to be only for 
i386. Without realizing it, the P4 CPU I picked is one of the newer ones with the 
x86_64 extensions. It won't boot i386. Thus, my plan B is going with CentOS4 x86_64 
and installing from the ATrpms collection. Here's someone who's already doing this:

- I picked up a cheap Radeon 7000 with TV out. Wrong! Various posts seem to say that 
the TV Out functionality is not supported by the X.org radeon driver. It *does* work 
with the vesa driver though. I just don't know if video and DVD playback will work 
with the vesa driver. Does anyone know?

- The stock RedHat kernel does *not* have irda support enabled. I downloaded 
2.6.13.2, enabled irda, and my motherboard's irda port is found and configured. We'll 
see if I can get it to work with the IR adapter in the nMediaPC case I bought.
