Are there any tricks to reading a faulty CD/DVD?

[Pottsey]

One of our teachers handed me a mini 1.4gig dvd that’s not working, it’s a film dvd from the school camcorder. The dvd its self looks ok and you can see the data is on there but half the computers I tried don’t read the disk the other half say its blank.

The only thing I am aware of is to try lots of different brand of DVD drives and hope one reads it. Any other options?

Thanks going to look up ISOBuster now.
EDIT: EDIT: Looking good so far, its sees the data just doing a long scan now.
