I recently connected my 360 to my PC so I could run my iTunes library through it. Unfortunately, I found that the dashboard and media player would not read any of the .aac files on my PC which is about half of my iTunes library (go figure). Anyone have any insight into a way to bypass this incovenience? I'd rather not convert all of my existing .aac files to .mp3 if I can avoid it (although improving the bitrate would be fine with me).
