If you don’t know what that means, don’t worry about it. If you were Googling to find out info on Sony’s PSP Media Manager software, save your time and money. I swore here that I would never buy, but then I did. Big mistake. Here are the reasons it sucks:
1.) It does not support VOB files (ripped DVDs)
2.) You have to re-encode a movie every time you put it on the PSP. This take hours.
3.) No intergration with any sort of playlists for music.
4.) It only encodes about half of the AVI files I have from BitTorrent.
I recommend PSP Video 9 now. Eff Sony.
