Thanks much for your replies, guys. I really appreciate it.
So the consensus is that it’s best to import the AC3 audio as a separate file into the dvd burning software and then bring in the self contained .mov of the video (with no audio) and smack them together for blu ray encoding?
Also, as an aside, would the blu ray simply play the audio as 2 channel stereo if the end user does not have DD 5.1 capabilities?
Thanks again!
