I'm trying to backup a two disc dance recital that my daughter just had. Disc one is the smallest and no matter what I have used, Shrink, Nero, it will not read it. The second disc worked beautifully with Shrink. Both discs play on my computer or a dvd player.
Are you just trying to join them together and then burn them as one continuous file.I did a holiday 2 disc dvd for a mate the other day.Its pretty straight forward and you only need nero recode.
Put the disc in your burner. Drag the directory called VIDEO_TS to your hard drive. If it copies, then just burn that onto a DVD (preferably using Nero and 'DVD-Video'). If it doesn't copy over to your hard drive, then the disc is probably defective. Use Decrypter but in I/O tab, check off the Ignore Read Errors box.
have you tried dogbomb suggestion and copied the disc to your hard drive.If that doesnt work another way is to download isobuster and try and recover the disc.Then re burn the data
