The other day I found a site that explains how to get AAC audio files from I-Tunes to play on the PSP. Unfortunately, after coming back from spending the weekend at a friend's house, I was unable to find the site again. I have done alot of searching and can not figure it out. The one thing I did find, said just to change the file extension to mp4, but that doesn't work. I get a folder that says 0 files, but still uses my memory. How can I solve this problem, and how can I get the files to display the artwork on my PSP (the artwork is present on all of my files in I-Tunes). I have both protected and unprotected (from ripped CD's) AAC files that I need to get to my PSP, and I am running firmware 2.5. Thanks in advance for any info/advice, as this situation is driving me insane!!
