I think you're confusing people, MeBeJedi. There is no PCM track on the ANH DVD, only 448k 5.1 DD and a 192 2.0 DD. Niether one is going to give you an uncompressed PCM track.

so if I use my original capture Wav file as a sound stream on my dvd, that could sound better than the converted AC3 file?

The captured PCM audio off the LD will probably give you better sound quality. I would recommend getting the center channel dialogue off the DVD's 5.1 track and mixing that in. That should give you the best sound quality, even if you decide to compress it down to DD or DTS audio later.

Edit: Do you still need the isolated center dialoge from the 5.1 track? If so, I'll put it up for you to download.
