Hey just put a tv show episode on my usb hard drive and connected it to my blu ray player with divx hd integrated so I can watch hi def files I download. Now this file is a mkv with what appears to be 2 audio streams, when I select it through my blu ray the picture appears but it says audio stream not supported on screen but then plays the other 5.1 stream fine. My question is can I get rid of the other stream so it does not come up with that warning anymore???
