Can't copy my own DVD-Rs

[racingintherain]

A few years ago I started burning my family home movies to DVD-R. At the time, I never thought much about logevity, but recently decided I better have more than one copy and that I should burn them on better media. So I started copying the discs. Today I've encountered one that is failing on all my attempts to copy it. Straight file copy, DVDDecrypter, DVDShrink, Nero - all fail with a variety of read errors.The dis is, however, playable.
Any suggestions?

Thanks.

try isobuster or test with another dvd drive.

Thanks Baldrick.
No luck with ISOBUSTER.
Did manage to get all but the last 2 VOBs with another try with DVDDecrypter.
Will try another drive in the next day or so.

Clean the hell out of it and try DVDFabDecrypter too...it's free...worth a shot.

Well Hech54, that did the trick. Sailed through it like there was absolutely nothing wrong. I'm sold.
