I would like to copy my non-protected music files to my PS3 console hard drive. The PS3 says it supports AAC files. All my files were ripped to AAC in Itunes but they have an M4A file extension. Itunes says that's an AAC file but the PS3 doesn't recognize the files with those extensions. I assume it's looking for "AAC" as the actual file extension. First, why, when you rip to AAC in Itunes does it give the file a M4A extension? Secondly, How do I convert or export the files to a "normal" AAC extension so the PS3 will recognize it?
