Can Anyone Help

[asriel]

I am currently using Datasafe 2x Speed White Top Printable Gen.4 V2 DVD-R media to backup my dvd films. This is the second lot of disks that I have used.

I had no problems using the first set, all films worked ok on PS2 and my Pioneer 105. But now when I am using this second lot, most of them do not even read on either player.

I have not changed my backup method which is copy all files to harddrive using DVDDecrypter, then DVD2One to resize to fit to one dvd-r and finally nero 5.5.10.15 to write the finished film.

Is it possible to get a batch of crap disks or os there something else that I might not of thought of which would cause me all these problems.
