I burned a blu ray file to a BD-RE disc that my magnavox paperwork says it will read, and my LG WH10LS30 DID burn the disc (25GB Sony) but when I play it on the Magnavox Blu ray player it tells me to "eject the disc...playback option may not be available on this disc". It was an mp4 file and I tried to transfer it to a disc but it said the same eject disc notice.. I think I converted it to a vob file which then transfered it to a disc. Please advise???
