I was planning on leaving the audio as it is. So, it will be an exact dublicate of the audio on the DVD. I think it sounds fine as well. :-)

Bah, 1993 audio with 1977 video? Such an anachronism shouldn't be allowed to survive. In my opinion, while I admittedly don't like the 93 audio anyway, it should at least accompany the 81 crawl to maintain some semblance of historical... uh, whatever. 77 video must have one of the 77 audio mixes.

Regarding the AR, did you crop off the left- and rightmost 8 pixels before stretching? Because those 16 pixels of blanking (NTSC only, PAL is a little different) are never intended to make it to the display device, and the actual usable image is 704x480. If you don't do this cropping, all DVDs with analogue blanking will make everyone just a hair too tall and skinny, circles will be ovals, etc... (but there's no guarantee DVDs will have the correct AR anyway even taking all that into account)
