One more question...In using Clone DVD2, when I go and pick my audio streams for the movie Wedding Crashers. it lists the following: English Dolby AC-3/6 English Dolby AC-3/2 English Dolby AC-3/2 English Dolby AC-3/2 Do I need to use all of them, or can I just use the top two for the six and two channel sound? Why is there 3 streams of the AC-3/2? I want to have the best audio quality. Thanks in advance!!! Everyone is great on here!
