I just started using MTR, and for one of my disks it read "intentional bad sectors on disk" and gave me two options. Either to "pad" or to delete the sector. I had no idea which one to use, so I just cancelled the rip. Now when I try to go back and rip the DVD again, about half way through, I can hear my drive having real hard trouble reading the disk it seems. The disk sounds like it starts to spin, my drive tries to read it and it slows back down. This happens over and over for a few minutes, and I really don't know what is going on so I always stop the rip. What is going on with these disks, and does anyone happen to know a way around it. Any help would be appreciated.
