I downloaded the NCAA Football BCS National Championship game off i-Tunes. It list it to be an MPEG-4, but shows a file extension of .m4v , once installed on the SD card, the Video Player recognized the file, but won't play it. Do I need to do something to the file or is there not a play everything type video player yet? I've played .mp4's before, why is this situation any different? Thanks in advanced.
