I would not have an issue with transferring stuff from one DVD to another any more than I do with putting Vinyl onto CD. To my mind, I've already paid for this and as long as the backup is for my use only, what is the problem? especially given the rapidity that catalogue material is deleted so quickly. Also, as pointed out, CD's get damaged very easily and we should be able to make our own copies. The current crop of Pseudo CD's that are hobbled & do not play in computer systems is also very bad - my understanding is that these are no longer true CD-Audio, but some kind of bastardized hybrid.
There is an interesting case going on between the RIAA and the Music publishers at the moment - the publishers are asking for double royalties on these discs that have both Pdeudo CDA & MP3 on them saying it counts as 2 copies. The RIAA used this argument against MP3.com, so they can't really complain even though they are crying foul!
Piracy is a huge problem, but the RIAA are not making any friends by suing their potential customers. Not going any further here, as I do not want to get banned.
