Dual layer problem

Can anyone help please?
When I copy onto Verbatim dual layer dvds everything is fine, but if I use Datawrite discs my dvd player cannot read them, even though they will play on my pc.

This is not uncommon. Verbatim blanks produce better results for many users. There are other forums in CD Freaks where you can get more information on blank media ratings and also DVD burners. If you are using DVDFab, check the box in Common Settings–>Write that says “Set Booktype to DVD-ROM” for higher compatibility with standalone players. Most burner firmware supports this option now.

I think that you answered your own question, use Verbatim DL DVDs.
