Can't burn dual layer dvd/s :(

Everytime I try it is unsuccessful, i am using TDK dvds and my burner is a SONY DVD RW DW-D22A.

Please Help.

Should I use different software or diif kind of dvds?
If yes which one?

You should only be using Verbatim DVD+R DL 2.4x (MKM-001-00 dye) made in Singapore burned at 2.4x. Your old burner is rated for 2.4x burning. You would have better success with a new burner.

how about changing the options to burn at minimum speed, would that work?

TDKDL is crappo crappo media. Get verbatim DL.
