That would be the buffer. When you change channels it buffers it for
a couple of seconds. I think the delay should only be 2 seconds, but
I could be wrong. Also, are you using an external cable box? If so,
there could be additional delay being caused by changing the channel
on the box, first.

I think you should open an SSH window on another machine and watch top
when you changing channels or bring up the program guide. That will
tell you very quickly if it is spiking your processor at those times.
I wouldn't think that it would the problem though. Maybe there is a
video driver issue?
As for RAM, 512 should be more then enough if you are just running
myth on the box.
