i hqave a movie that is in quick time format that i want to put on dvd ,but when i use tmpegnc for it , it starts out good but after a few minutes it starts to slow down till it almost stops and where it tells you how much time is left to go it goes up to 38 hours. then eventually it freezes and it says not responding. in enviremental settings in the plug in section i put quick time at the top of the list. am i doing something wrong or is there another way i can encode this? any info will be great.
