Something is wrong then - unless you're watching some weird HiDef.  I've got a 1.6GHz Core2 
laptop running a 1680x1050 display as a front end... That can almost keep up with the BBC 
hidef streamed over my powerline network connection.  I think it's possible that the only 
issue is actually the lack of stability in the network stream.

The main reason I've been looking to do it (Xen) is to allow me to have a very stable OS 
platform that allows me to test new versions of myth more easily - as well as give me the 
separation/isolation I like (I'm paranoid).  My plan was to run CentOS as the main OS, and 
then have a fedora (or similar) backend running in a domain.  It would give me the ability 
to snapshot the backend, do the upgrade, and if anything didn't go to plan just rollback 
really easily/quickly.

There's that too :)
