what dvd burner are you using?

Well I need to buy a DVD burner because the one I have now is not one. Here it what I was looking at. Will this work for dual layers?

 Can all DVD drives and DVD players read dual layer DVDs?

Yes, that linked burner burns DVD DLs.

I believe so.

Movie?  Just wondering, DVD Shrink might come in handy.

DVD Shrink is a great solution for movies. I use it daily, haha. 

But to the OP, you need to be careful with dual layer DVDs. Not only are they expensive, but a lot of times  DVD players (if the disks are movies) have trouble playing them.
