I had this problem when my machine was "fresh out of the box" as well. I found 
that setting mythfrontend suid root fixed that. Not perfect from a security 
standpoint, I know... but the box is well defended behind a firewall and its 
own internal firewall.
 
Another possibility is memory. Or possibly something that's running in the 
background.
 
Oh, one other possibility would be filesystem in use on the video partition. 
I've found (through trial and error) that XFS is by far the best filesystem to 
use on the video partition for general use. It deletes instantly, almost never 
seems to get fragmented or "busy" and generally is a nice FS to use. I tried 
ReiserFS (kept trying to rewrite journals while I was trying to watch TV) and 
ext3 (fragmented too easily for my tastes)... though I've been led to believe 
from a friend of mine that you can use an ext2 partition for buffers so long as 
you keep 'em below 2Gb. That apparently works well.
 
As mentioned before, it could also be MySQL... but to be honest I doubt it. 
Normally MySQL is pretty solid and doesn't just randomly do stuff unless you 
tell it. However, I wouldn't rule it out.
