If you're making a backend only, the TV out on the box itself should
be irrelevant, making a 350 vs a 250 a moot point. If you have a 350
already, it will work fine.
I personally would go for an Arch linux install. It gives all the
benefits of a real distro in being easy to install new software,
update, and being readily available. It also has a very active
community, and allows you to use i686 precompiled packages or rebuild
your whole tree. It is much snappier than knoppmyth or fedora. I
compare it in speed to be somewhere between stage 1 and stage 2
gentoo. If you compile the whole tree, it feels faster than gentoo can
be. Arch is just easier to install than a LFS solution, and still
provides incredible flexibility. Arch isn't made to hold your hand.
If you can pull it off, I'd also go for a faster processor if you want
to do concurrent recording and transcoding or commercial flagging. The
Athlon 1.1 will be more than adequate for any one task, but it will
take a long time to transcode things and may "cramp your style" as you
get used to mythtv's functionality.
Also, just because the DXR-3 is a creative card, it means you should
run away as fast as you can. :)
