Believe it or not, VLC won't play the audio of m2ts either. And the video is a bit jerky though this is the first problem I've ever encountered with that fantastic program. Media Player Classic plays it fine, although, and this might be a purely subjective opinion, the video resolution seems better with WMP. I've looked into the converters and as they don't seem to involve any loss in Blue Ray quality. I could go that way. Thef thing is though, call me stubborn, but, if WMP 11 does in fact support raw m2ts than why don't I get the audio, or do I need to download a codec? It faultlessly plays all other file types I've thrown at it. Thanks
