I have a 4 Quad 8 M processer, 640G Hd, Win7,64 Bit. Should it take 6-8 hours? That is after using Anydvd to put on the hard drive.
That doesn't answer the question. What version of Rebuilder are you using? What encoder are you using? Do you have it set for multiple encoders? Can you post the log file?
You definitely have issues. My 2.6 dual core only takes 60-70 minutes on avg. You need to answer the questions dialysis posted to help get you going.
