I have a DVD that my Kid scratched up with surface sratches (not very deep) just a good volume of them The disk seems to play, but when I try to copy if it craps out during the "analyzing". I get the Read error 400. Is this scratching or other type error. I hate to lay out the money to replace the DVD if there is a way to recover this disk.

I try to keep my originals away from the kids, but I geuss I failed this time.

Error 400 is a general read (transcoding) error...doesn't tell us us much in terms of specifics.
Try cleaning the disc first...just windex, isopropyl alcohol etc. and a decent microfiber cloth.
Since you can see a lot of surface scratches, probably go to step #2.
Brasso polish and the same type of microfiber cloth.
Brasso works great as long as it's not gouged...

try DVD Decrypter and a PSL file if what Maineman recommended does not help.

Google with "DVD Decrypter PSL2"

DVDFab Decrypter (free version) could also be of help.

Hi flopguy
Try using ISO Buster it works some times with scratched disc's if they are not to bad, it will extact the files to your HD

Thanks guys for all the ideas, It turns out that there must have been too many tiny scratches. My friend at work has a DVD resurfacer (some kind iof crank kind) and it did a pretty good job of it. I was able to use platinum to burn it successfully. I think I might pick up one of those resurfacers.
