I have to agree with David. I always export to .avi and let Encore handle the encoding. The other day I decided to let Premiere encode to mpeg. It was 9 hours at 4 to 6mb variable rate for 1h51m project. This is on a dual xeon 2.8g with 2 gig of Ram. I killed it the next morning when it was still running. Same project this time exported to avi in less than an hour. Encore had my dvd completed and playing in just over an hour
