For what it is worth -- given that so much time has passed since the last posting on this thread -- I use Adobe Premiere Pro 2.0 quite a lot these days. But I *never* use it to produce an mpeg-2 for precisely the reason Carole outlined in her last posting. (The file with the .m2v is in fact an mpeg-2 file, but only contains the video stream. I am sure someone will have a more technical explanation. Adobe also produces a separate audio file, though I am no longer sure which of the two others mentioned by Carole is the audio in question... And of course, using Adobe Encore or even After Effects, it is possible to insert these separate files into their relevant timelines and author a disc. But all this seemed just a touch too complex and worrying for someone at my current state of video development. Hell, I am only at the stage of no longer taking a deep breath when I even open Premiere!!

And after 4 years of using successive VS versions, I am only just now venturing into the perilous waters of Workshop...)
Instead, I produce a final DV/AVI in Premiere (File > Export > Movie). Then I use Video Studio 10+ to convert it to a DVD-compliant mpeg-2. This is a straightforward and usually fairly quick process (taking usually less than real time on my computer). And then I insert the new mpeg-2s into DVDWS for authoring a disc...
I guess DVDWS could also convert the DVs during the authoring process> However, since I constantly recommend against that work flow in the VS forum, I tend to follow my own instruction even here!

And this way, I also get to preview the mpeg-2s to make sure everything is OK before I insert them into the authoring process in DVDWS.
