Default MP3 Bitrates also Jitter

Seeing Stimpy's post where he mentions 320 Kbit MP3s has got me
wondering.....

I recently re-recorded my 'Top 20' CDs/CD rips at 256 Kbit due to now having
the space to be able to do it and they sound absolutely fine - good enough
to fool the 'Golden Ears Brigade' representative, hereabouts, a few nights
ago, as per my recent post.

I seem to remember someone somewhere saying that the highest rate MP3s can
be spitchy and wonder if anyone here can confirm or deny this? I haven't
heard any such thing myself on the 320s I've tried, but I don't want to put
a lot of effort into 'upping the rate' if there's a possibility I'll regret
it in the future. (I also can't hear much difference myself, but that means
nothing....!! ;-)

Also - playing MP3s from a computer's hard drive - does this remove/reduce
any problems from Jitter? Where is the sound coming from when you play an
MP3 thus - is it read into RAM entirely, if so I would have thought would
remove the possibility of jitter, but would jitter have been already
recorded into the MP3??? Is there any possibility of jitter being 'ironed
into' a recording and then getting 'jittered again' when it's played??

(Although, once again, I can't say I've ever heard 'Jitter' myself - I'm
confused and it, er, gives me the jitters...!!??!! :-)
