Do I need to mux to keep sync for authoring?

I captured a vhs with advc 100 into dv type 2 avi with uncompressed pcm. I have edited in vegas 4.0. Now I want to convert the video to mpeg 2 and the audio into ac3. I was going to use TMPGEnc instead of Vegas DVD architect as it performs 2 pass vbr whereas Vegas only does 1 pass. Unfortunately, Besweet wouldn't convert my pcm into ac3. I know that vegas 4.0 converts it but it seems I would have to convert the audio to ac3, then I would have to convert the video to mpeg 2. I don't seem to be able to do them at the same time. I had been thinking that this wouldn't be a big deal because, having my avi as a type 2 dv file, I figured I could encode the video and audio separately, yet because it is a dv type 2 file, they would still be linked and there wouldn't be any resultant sync issues once I went to author.
Now, I am wondering if I have to mux the audio & video after I convert them to mpeg2 and ac3? I believe if I want to use dvd architect I will have to mux them together as the manual states that "mpeg elementary streams are not supported. Even if you plan to relace the audio with pcm or ac3 , you will need to import muxed mpeg files" If this is the case, I am not sure how to go about muxing the audio and the video so that I can use them in dvd architect (once again, I initially thought the fact that I had a dv type 2 file, meant that I could keep the audio & video together, yet process them separately). I guess the other way I could go is to encode the video portion in TMPGEnc to mpeg 2 in an elementary stream with no audio. I could then encode the pcm audio to ac3 using vegas 4.0 (as I wasn't able to do it with besweet) and then (I guess) load both files into TMPGEnc Auth to do my authoring. This whole area leaves me a little confused so any advice is appreciated.
