I've been backing up dvds using AnyDVD and dvd shrink for quite awhile suing regual DVD+R discs with no problems. I am now trying to use some DVD+DL discs but my computer won't read them. The first time I put the Dvd+DL disc in it kept asking me to put in a compatible disc and it lists off what the compatiable discs are, and DVD+DL is listed. and when I have no programs up and stick the disc in the drive, it doesn't do anything but act like it's scanning the disc for about 30sec, then the drive just stops. I tried double clicking on the drive to see what happens and it says the disc needed to be formatted, so I tried formatting it but then it said it couldn't be completed. I don't know what to do, anyone have any sugestions? I also am using Windows Vista if that's important. Thanks.
