Camcorder DVD-R, can't copy

Hi,
I have a DVD-R camcorder. I recorded a video of my son, finalized it, and can watch it on my computer (and DVD). There was a small, brief “drop-out” of the picture in the middle of the DVD, but it didn’t lock it up.

I’m now trying to make a copy of it for the grandparents. But, it keeps giving me a read error and won’t allow me to copy it.

Anyway around this?

Thanks,
MM

What program are you trying to copy it with???
Have you tried IMGBurn?
