Right.  Though you can make even an Atom work well by getting rid of 
stuff--after all, that's exactly what Intel did (they took a useful CPU 
and cut out stuff to make it hit their TDP requirements).

So, just start deleting recordings (and/or moving them to Video 
Library--which isn't a bad idea on Atom or with better CPU's) and 
recording rules (Manage Recordings|Recording Rules, then set rules to 
"Do not record this program") and recording history (Manage 
Recordings|Previously Recorded, then MENU|Delete Episode or "Delete all 
episodes of '<show>'").

Of course, this is the "bend my expectations to the underpowered 
hardware" approach to using MythTV.  Personally, I prefer the "right 
tool for the job" approach, but hey, feel free to hammer those screws in 
with that saw you picked up if you like.  :)
