I'm running an Atom 330 with an NVidia ION and 4 gigabytes of RAM on a 
combined fe/be - max CPU on Live TV is 37% and max mem for mythfrontend is 
4.1% mythbackend uses 10% of CPU and 2.0% of RAM  (according to top)- and 
fe/be are the largest consumers of resources on the system.

I use the VDPAU Normal setting for playback as well.

I can watch a recording / live tv, be recording and run a mythfilldatabase 
without any performance hits at all; I've even been watching a recording and 
compiling at the same time without even noticing.

I have also noticed when I do a retune I don't pick up the MHEG only 
channels Vision, Connect and Stream even though my TV with Freeview built in 
does.
