It puts the data on my computer perfectly, but when it goes to burn them, it gets half way through and says there's an error so i ruin a disk.
We need more information. Burner drive model, brand and type of blank media and programs use. You say you are using Shrink, but Shrink doesn't burn so you must be using Nero or Decrypter as the burn engine. Also it is a good idea to use a RW disc when first learning to burn dvds. That way if it errors out you don't waste a blank disc. Jerry
Shrink will not burn DVDs,It will however put the ISO of the movie onto your hard drive, download either decrypter or burn4free and burn from the ISO.
