I get the same error message, "source data too large", on two different computers using four different DVD burners every time I try to clone a DVD ever since upgrading to this version.
Please don't offer me any the remedial suggestions that I need to choose DVD-5 or that I need to upgrade either the software or firmware for anything, or that I need to delete other video-related softwares. I have already done all of that.
I have been very successfully using ALL of Slysoft's products for almost two years now and have not had an issue like this in that period of time. I really need an answer to this problem that doesn't treat me like a novice. I am not.
I see this problem on every cloneDVD forum I have visited but so far no one has come up with an answer other than the silly remedial offerings.
