Um, didn't I answer that further down? Oh, look! Yes, I did.

You asked: What would be a good amount of RAM to upgrade to?  Over 

I replied: I find 512MB to be more than sufficient. I'd recommend 384 
as a minimum (256
can be used, but you'll see swapping, which I prefer to eliminate).

The UI, the database, commercial flagging, scaling video to fit the 
screen, deinterlacing video, the OS itself, etc., all use memory. With 
only 256MB, I've seen a system start to use swap. Touching swap impacts 
performance, and RAM is cheap. Both my active Myth boxes have 512MB.
