Most of my Movies were encoded for an Apple TV using Handbrake. As such they contain a 5.1 encoded AAC fileas Audio One and a 160kbps encoded AAC as Audio 2. When playing these in Mediaportal, which I am moving over to, I get no Audio. I have FFDShow and AC3filter installed. I'm hoping to use these files without having to reencode all my movies. They were originally .m4v files which MP will not recognize, I've renamed them to .mp4 is this causing the issue ? Anyone have any ideas?
