Thanks Moth3r, got it and made the disc successfully with Dr. M's version. There's only one problem...I'd really prefer the original PAL mono-mix! I still like the video quality far more in Moth3r's original, and I also realized that I can't make a disc with the mono-mix as a bonus audio track when using the NTSC version. Since the PCM track on Dr. M's disc isn't recognized by dvdauthorgui (as far as I can tell), I can only make a disc with just the mono mix. With Moth3r's, the original audio is an ac3 file, and I know enough about dvd authoring that I could make the dvd a dual soundtrack disc simply by adding the mono ac3. I realize there are likely ways to get around all this, but I'm new at encoding and authoring and all that... I really have no idea and can't seem to figure it out from the information I've found on the subject.
I guess what I'm saying is, if at some point anyone on these forums can re-upload that original PAL mono-mix file anywhere, I'd be grateful.
