Many writeable DVDs of that age will have deteriorated, especially if not kept in the dark, to the point that the data becomes sufficiently corrupt that the drives can't handle them; error handling in these cases is abysmally bad in all drives, and locking up completely is quite common. The only chance is to continue to try different drives in the hope that you will find one that can manage to read them.

hmm. Does Windows have an analogue of the dd command?
Barmymoo:
The DVDs worked a couple of times today, as long as I restarted the computer with the DVD out of the drive and the drive not plugged in, and then plugged in the drive and loaded the DVD once it had fully started up. I still couldn't get the files copied across though.
hedgie:
I suspect that due to the damage to the dyes in the dvds, that the copy is failing due to the error-correction bits of the copy utility, but if you have playback, the errors were able to be handled properly by whatever media viewing software you were using. If you have anything that can just clone the disk, instead of the normal copy procedure, that may help you avoid the copy failures (the drive's error-checking might still cause a few headaches, though), and get the files onto your HDD. Someone here who knows more about Windows than I do might be able to do a bit more in that regard, but I found this with a quick search: http://lifehacker.com/5839753/the-best-disk-cloning-app-for-windows If things work properly, it'll be able to perform a perfect copy (errors and all) of your dvds onto your hard drive.

^ This.
You could also download a decent file-copy program such as TeraCopy :)
