Camcorder DVD Unfinished

HI all
I got two mini DVD-R that were burned in a Camcorder.
Both of them are unfinished, so I can only pay them using Burning Software.
How can I finalize those discs with my PC?

I dont have the camcorder here!

Thanks

Cant you just pull off the files and burn them to a regular DVD

How? With what program?

What form are they in. do they have extensions. No doubt the camcorder web site has something you can use to see and pull off the file / files.
If you can see them you should be able to do a copy paste onto a hard drive.
If you can watch them with a burning program they must be some commen type.
