I have been using shrink for a while now and all of a sudden the encoding -backup of a movie went from approx 15 minutes to about 2 hours on the same pc. Nothing esle is running. I have a 2.0 P4 with 512 ram. I defragged the drive just to see if it would help, but no luck. The option for a better copy isn’t checked either. I un-installed and reinstalled 3.2 as well.
Try DVD Decrypter. What are your approximate min and max rip speeds?
