Burning DVD's

What is the best program to burn DVD’s on? One that recognizes codecs etc..... I have Sonic, but it won’t burn what I want. Thanks for any help.

DVDshrink
The best and free.

Wyman, I went to DVDshrink but it’s not free. It will only allow entry after I agree to which "pkg" I want to buy. Am I in the wrong place?
