I have a lot of music ripped to my hard drive in SS. I've used to the ATRAC3plus encoding, and they are saved as .oma filles. The PS3 supports ATRAC, as I've ripped a few CDs to it's hard drive using the PS3 BD ROM drive. When I rip music on the PS3, then transfer it to my PC, SS recognizes the file, which has a file extention of .aa3. I would like to be able to transfer the files on my hard drive to the PS3, but it doesn't recognize the .oma files. I realize I could re-rip everything but that would obviously take a lot of time, and I'd rather not go that route. I could also convert the files to MP3, but I'd rather keep them in ATRAC format. Any thoughts would be appreciated. I posted this on a MD forum, and someone suggested trying here.
