DvD(s) reads in player(s) not on computer(s).

I bought a box set of DVDs several years ago. They have always worked great in my at least 3 DVD players, but fail to show ANY data when trying to view them on different computers. (XP/Win7)

The result is the same for several DVDs, work great on several stand alone players, but fail to "load" in a computer DVD drive. On my XP computer it just does nothing, on my win7 machine the dvd player grinds for a while then says unable to load application e: In each case, with every DVD in question there is simply no data. In any case it acts as if all of these DVDs have no data on them.

To be clear, I have no problems loading any other DVDs on my computers. Just this set of DVDs.

I would like to back up these disks before they die. I assume I'm facing some sort of copy protection, but I do not know..

Any advice would helpful.

IMO, that doesn't seem like a hardware problem of any sort...in fact, it almost has to be a media issue...but it really makes no sense at all to me if it's not a media issue.

Well, I'm not very familiar with these forums. I guess I posted in hardware because "one one hardware set it works and another it doesn't"

I'll try posting in another section..

No need to repost...the problem as you describe it...belongs here as much as any other forum .

Wait for comments from others, please.
