You mean more than 2-pass? CinemaCraft is one I know.
I can't agree that 2-pass is bad, mostly there's very little diffrence between 2-pass and x-pass encodings. Better choose your video bitrate correctly and don't try to fit 3...4-hour video to 4,3GB disk.
Most of my work is very short 3-5 mins. I just can't seem to maintain a sharp image when I go to DVD. Not sure why.
I'm working on a mac and using FCP and Compressor. The Presets on compressor just are not clean enough and there is not a lot of finessing allowed in the program.
Cinemacraft looks good but is VERy pricy and PC only.
I've made so many passes at bitrate changes I'm going insane.
