Essentially what I'm doing is making a complete backup set of my DVD library and then putting the originals away and using the copies as my primary discs.
So, I use DVD Decrypter which puts an exact copy of the DVD on my HDD, without the copy protection.
Then I want to burn that to a disc.
I used a version of Nero I got with my previous DVD burner and that worked fine but it doesn't seem to want to work under Windows 7, even in compatibility modes.
Most free suites, including the burning utility included with Windows, doesn't recognize the decrypted files as being media that can be burned. And even if it did, it wouldn't recognize the VIDEO_TS folder as being important, nor would it understand that it's a movie inside.
And the free version of Nero doesn't support burning video DVD's.
IMHO, you are expecting too much for a Freeware program. All the well known DVD burning suites cost money.
