Hi. I have used dvd shrink to encode many movies. Most of the time the job takes about two hours; sometimes a little more for longer movies, TV sets, etc. However, sometimes the job gets done in 25 minutes for a 90-min movie. Which is great - but I can't figure out I did something different, if it's a fluke, or what. I settings/preferences are the same every time (and I burn from VTS folders). Thanks.
