Again sorry how hard it is to read what i type as it just seems my thoughts run together when i type.. Starting to re-read my posts.
Just a litle history about thing..
Mpeg 1 specs have different choices.. they have the file format of Mpg but they have Mpeg 1 video standards and there is actually two audio formats called Mpeg 1 Layer 2 audio which is generally refered to as mp2 which you hardly ever see and the more common which you already know which is actuall Mpeg 1 layer 3 commonly known as Mp3 ;o) it was acutally part of the mpeg 1 specs.
Now you have Mpeg 2 which is used in dvd's and besides that i don't think there was a new container or audio to go with it.. and now you have
Mpeg 4 which has spec for a container commenly know as mp4, the video codecs which DivX 4+ and Xvid and Nero Mpeg 4 codecs are all Mpeg 4 videos but they are but they all kinda support different definitions of all the mpeg 4 profiles. which are defined so that you make standalone players support certain profiles and if the codec properly encodes to the profile then the standalone player will support it. And for Mpeg 4 the audio choice is AAC (Advanced Audio Codec) and is actually really nice and does better then Mp3's.
Also i think if i remember right Apple's latest Quicktime codec uses Mpeg 4 as it's video format and .mov files are just containers to hold the video data which you can place different types of videos in teh containers.. (Same as avi is just a container)
I know this is a long format of what i just posted above.. maybe a little bit clearer. also a little bit might be off as i am totally recalling from memory which you know how that can be.. BUt when i get home (At work atm) i will check that link.
Though can you post to the software your using or does it come with the Psp.
