I've been trying to encode a 2 hour mpeg and have tried every VBR setting ( 8000/4500/2000) etc. and video looks blotchy during fast movement is there something I am not doing? Is it possible to get 120 min of very good quality with ac3 under 4 gigs? I am using VV 3.0, DVDit PE used Main Concept and TMPEG. Thanks, Anthony

To get the bitrate down and keep the quality you have to spend a small fortune for software. The industry standard is Sonic Scenarist (upwards of $20,000) and it's a bear to use from what I understand.
Even still, burning to DVD-/+R isn't going to give you the best quality even with that progtram. Hollywood type DVD are replicated from a glass master. Any places who do replication usually require a minimum order of 1000 copies.
There are other programs, but DVD (IMO) is one of those formats which will drop in price over time. Given the popularity of DVD's I don't think it will take that long either.
Why don't you try splitting it into two DVD's for now.

Yes, you can get good quality 2 hours with your software. Stick with Vegas and set the Average bitrate to 4,800,000 Minimum to 2,000,000 Maximum 8,000,000

Next, make sure the "Quality" slider is on 31 (mine defaulted to 15)

I also set the DC Coefficient to 10 bit.

Try this file in DVDit PE using AC-3 and you should see good results.

Try using a DVD authoring program that does NOT rerended the file. I use DVD Movie Factory which accepts the file as rendered as a MPEG-2 in Vegas and the results are excellent. The only limitation is the DVD menu templates are limited, but I'm not about to pay hundreds of dollars for a DVD authoring program only to get "better"
menu templates.

DVDit PE does NOT re-render the MPEG file. Also, it adds more than just "menus" - try AC-3 compressed audio.
