double layer dvd problem

About a year ago i have burned a concert on a two double layered dvd's.
One day i was watching it, finshed an put it back to the box. Next day i tried to run it again and it wouldn't work since then. I tried other dvd players or even other home theaters.
SOlution?

 

Hi.

Will DVD Decrypter or DVD Shrink rip the disk back to your hard disk?

Will IsoBuster open the disk?

Thanks for the reply btw.
You see that's the problem, the discs are read like they were empty.

 

If ISOBuster can't open the disk and find data, I'm afraid you're out of luck unless your DVD reader is faulty (which is always a possibility). Have you tried playing the disks in another drive on another PC, not other standalone players?

 

Yes i've tried friend's computer and my dvd home theather. But the strange thing is that both dvd's were working, but over the night... next day they just didn't work anymore

 

What brand were the DL disks?
