I probably have posted this suggestion on these and other forum before, but just in case here i go again. this my be just my opinion, you are welcome to desagree. With new encryption comming in almost every new movie that comes out, i don't allow my ripping and compressing to be done in one step. Even with anydvd, the best decrypter there is(which i do have). I always rip the movie to the HD first with anydvd or fabdecrypter, then i use one of my favorite programs, recode2,shrink,dvd2one, to compress. No decrypting on the fly for me, so no errors. oh yeah, i forgot, allow the burning part of the process not to go faster than 4x, i do 2x.
