I wanted to back up my Criterion Collection DVDs. I wanted to keep them on dual layer discs because I wanted to preserve the picture quality. I tried burning a DVD-5 using Recode 2. It doesn't look good especially black and white movies. Anyways, I ripped the ISO using decrypter. Then burned the mds file. At %50, it'll stop burning. It happened every time. I wasted $20. Where's the problem? Is it the drive or the media? Burning regular DVD-Rs is not a problem. It's batting 1.000 at that. anyways, I'm going to try the DVD-RB method next. I'm sure this'll work but I'd prefer to back up a dual layer version. Thanks for your help. Bye My specs are: 1.3 ghz celeron 1 gb ram I/O magic Dual layer 16x int. burner 100 gb hard drive (ntfs) I used Verbatim dual layer discs.
