If you can change the multipler in that board, it might be worth it.
Otherwise, ditch it and get something like this
http://www.newegg.com/Product/Product.asp?Item=N82E16813138234 .
That's what I run. A mobile XP 2800 on it running at ~2.08Ghz with
166x12.5 . I think it might only be 1.45 vcore too. In any case, it's
cooled with a 120mm fan pulling air through small holes in the top of
the media case and blowing down on the CPU heat sink. There is no
small fan attached to the CPU heat sink itself. I use the onboard
nvidia video and run 1080i HD streams with deinterlace just fine. This
machine is PXE booted and pulls an NFS root from a server.

There are a lot of ways to build mythTV and get it to work. I
generally pay a few extra dollars to save myself a lot of pain later

Why did you get a USB 2.0 tuner when you didn't even have the USB 2.0
card? Hawk it on ebay and get a PVR 150/250 or 500 ... depending on
your needs.

While were at it.... You didn't mention anything about HighDef
programming.... If you're not going to do HighDef (or many tuners)
there really isn't any point in going through all this pain to upgrade
the CPU and memory... the Duron will be fine.

It will work if you check your BIOS and see if there is a manual
multipler adjustment... but again... why all the upgrades for standard
def TV?

Not to fan the distro war. ( Honestly ) but this seems like your first
myth install. I would suggest Ubuntu. If you have experience with
Debian, you will be right at home, and you'll find more community
support for all the problems you'll encounter ( there are many many
ubuntu mythtv users )

eh, not really Kurt, I just get the task done and then enjoy the shows ;)
