Hey buddy...relax
Let´s see if we can help.
First we need to understand your question a bit better.

You have some home video you want to put on a dvd?
Your camera records on a dvd?

What´s your computer set-up? System, drive, software...anything you can tell us.

Have you done this before?...it worked?
Does it still work with other discs you have recorded on as well? It´s possible you may have to re-install the Sony software for example.

I mean there may be a simple solution, or a heavier one.

I´m sure someone here will know the way...hang in there.
