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.

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.

Hi,
One way to back up your DVDs is to simply go from DVD player>DVD recorder. Time consuming but worth the effort. I have archived many old VHS tapes by going VHS player>DVD recorder and then made a second DVD copy. These DVDs play well in my computer/laptop,Win7. Use good quality blank DVDs for your copies and be sure to 'finalize' the copy when finished. If your original DVDs are commercially produced then yes there might be copy protection issues. Good luck!

DVD player>DVD recorder? DVD recorder is software, hardware or what?

Hi,
Hardware - DVD player is just that. A DVD recorder is the same but it can also record programs from your TV or another player to a blank DVD.(Do not use a CD) Check your DVD player/recorder handbook for instructions about audio and video connections and recording to a blank disc. Link the player to the recorder which then links to your TV set so you can see what you are doing.You can stop/pause/edit as you go along. Just experiment and once again - good luck.
