I just had my dvd-r drive replaced (Matshita uj-11, I think) and I can rip a movie and back it up with Shrink but I can't burn it. It is writing but nothing is transferrd to the dvd disk and the stand alone dvd player says no disk ot format unsupported ( I tried two different dvd players). I was using DVD Decrypter and IMG Burn but neither worked so I uninstalled both. Maybe there was an installation problem. I'll try anything at this point. I can view the movie on my computer but I have to erase it because I need the disk space.
