[mythtv] MythTV and priority

Hi everyone,

Since I just sunk a bunch of money into my mythTV box to beef up its
encoding/decoding performance, I had to help justify that purchase by
teaming the myth functionality up with some personal Web/DNS/Mail services I
plan to offer from the same box.

So my question regarding priorities is this: What happens to the encoding
and decoding when another process (say a web or email server) starts serving
connections?  Is there a way to guarantee that Myth always gets the CPU
juice it needs, starving the other 'less important' processes so that my
recordings don't suffer any dropped frames?

If anyone on the list is doing similar things with their mythTV boxen, I'd
like to know what the results have been like, and more importantly, what
changes might be in order to guarantee the appropriate priorities are
achieved.  45% of an AthlonXP 1700 w/512MB RAM is still a lot of juice to be
giving a personal web server, DNS, etc... :D

Any help would be greatly appreciated, and might help start some looking
into a mythDNS or similar plugin... ;)

Cheers,
Chris
