Problem when trying to save with Sonic MyDVD

[TheManuel]

I've been trying to use Sonic MyDVD which came with my LiteOn 401s.
In order to burn a DVD, I have to save changes first.
Whenever I try to save, I get an error that reads something like this:
"Can not performthe requested operation - parameter error (-16701)"
The wording and number are not exact but close.

Has any users of that software run into this particular problem?
Any solutions?

Thanks.
