i use dvdshrink to make backups, and it always rips to the hd first, so i also would like to know how fast it rips to the hard drive for lets say a 7 GB Movie
the fastest your going to want to burn a movie at is 8x and even that can be to much. I usually use 4x but if im in a hurry I go to 8. I would never suggest going higher then 8x for burnin a movie or you will get some crazy skipping.
