It depends on your setup ... if you have a capture card that does Mpeg
encoding then CPU power is not an issue. I have an 800Mhz Athlon XP
(under clocked) system running a backend.  The issue usually is if the
box can keep up with the disk IO doing recording and streaming at the
same time.  I have two drives in the box, one for the OS and another for
storing the video.  The system does fine streaming to a front end at the
same time it's recording std cable TV.

Adding file services with lots of IO might cause problems, it depends on
the exact load your putting on it, adding RAM and using RAID 01
(mirrored and striped) may work.  If you had issues, build a cheap
sempon system to do the MythTV duties may be cheaper than making the
server capable of doing both.

One note is RAID 1 is slower at writing that a single drive, but usually
faster at reading.
