...but I'm gonna ask it anyway! (Sorry if it's a bit long).
Why do I need to decrypt the VOBs etc. from a DVD just to burn it on to another (blank) disk?
The way I see it (naively, perhaps) is that if I have a bought disk, and want to make a backup in case the kids scratch it (or Blockbuster want it back), I copy the contents verbatim onto my HD, then copy those files again verbatim (in the same order if necessary) to a blank media disk, and let the DVD Player take care of de-crypting the data - it's what it's good at...
An analogy: If I have a Fench novel, I can scan the pages, (optionally OCR'ing them to get the ascii-bytes which made the pages, it makes no never-mind) to create an 'image' of the pages, save said images on my HD, then print those images (which might be pages of ascii) onto paper, staple them together, and hand a Frenchman (sorry, Frenchperson) a perfectly serviceable working copy of the original novel. All this is done without de-crypting (i.e. translating) the 'data' (words/sentences) into plain (English) - there simply was no need as I was never going to read the stuff.
Likewise, copying the DVD 'data' just to make another identical disk doesn't require that the PC 'understand' the data - data is just a stream of 0s and 1s whatever - an encrypted file is just as unreadable (or readable) as an un-encrypted one - 0s and 1s are always 0s and 1s...
I just know I'm gonna got shot shot down for this, but hey, I'm a newbie (that's my excuse) and anyway, healthy debate is good for the mind ;-)
I'll just sit back now and watch the fireworks!
