When I try to copy a VOB file from a DVD to my hard disk, and it says "error copying file or folder" and says "cannot copy ....: Cannot read from the source file or disk." or "cannot create or replace.." Is that dvd encryption? or copy protection? or both?
I have a burner that will let me drag a commercial DVD VOB off the disk and a ROM that won't. The one dragged off the burner still has the protection and is not playable -content is scrambled.
I don't know what you mean at all. Does this have anything to do with whether the drive does writing(what you call a burner), or is a read only drive? I think the drive has nothing to do with it. It shouldn't make a difference to this. The question revolves around the nature of what is on the disc.
It is neither here nor there. You question was answered jut fine but you are confused. The more important statement, is that if it is a commercial DVD. The files are encrypted, so chances are no matter what you are trying to do, you are going to fail the way you are going. Check out the shrink forum and just read a dozen or so threads. That forum is all about backing up commercial DVDs using freeware/shareware.
I wasn't asking how to back it up. I managed that pretty much even before I asked the questio, just downloading some freeware and clicking go/start. I was asking a technical question. His answer requires interpretation. I would guess, that his disc didn't have copy protection. But did have encryption. And his "dragging" didn't use any special software either, just the OS. So I would guess that the correct answer to my question, is that the particular error copying message is just from copy protection, and would appear whether the DVD was encrypted or not, though they would be encrypted on a commercial dvd. Commercial DVDs are all encrypted.. but is the answer right in suggesting that copy protection isn't as common? I also see no answer to the obvious question of why his DVD-ROM drive won't let him copy a file off but his DVD Burner drive will. If that even makes sense, and it doesn't seem to.
The answer was neither encryption or copy protection it has to do with the capabilities of your drive.
