I finally got my ntfs drive going, now I want to back everything up on dvd.
I insert a dvd+r pick my files to burn, click the write disk thing and then it says the disk isnt supported... ok they are standard 4.7gb dvdr's I put a different one in but got the same thing,

I know this sounds silly but I got the same thing a while back, it turned out that I was trying to burn slightly over the capacity of the dvd.

Does this drive burn these DVDs when you try it with another distribution or with Windows?
If it does, the problem is with your OS or your DVD burner program.
If not, you will have to make sure you have a correct match between your media and drive.

What is the make and model of your DVD burner?
What are the formats that it is supposed to support.
What is the brand of DVD+R media?
What DVD burner program are you using?
I use K3B. If your DVD burner program isn't performing, you may want to remove and re-install it with Yumex.
