Re: dvd burning program?
To create the ISO or to burn the ISO to a disc?
For burning, Imgburn is probably the best program you can get.
For creating, ConvertXtoDVD. It's the only one that's ever worked for me personally.
It's not free, but you can find it on TPB. I have ConvertXtoDVD.v126.96.36.1993. Just search that, you should find it.
