Burn message using ConvertXtoDVD

Can anybody help, as the title says im having problems with convertXtoDVD, I’ve tried a few times to burn but am getting different error codes. This is the latest one, It says: Illegal request, LBA out of range. I’m only new to this so im not sure what the problem is. My Uncle set up all the software for me in his house and successfully burned a movie using his discs, maybe its the dics im using, Mirror Dvd-R x16 speed, 4.7GB. My Uncle did say that not all discs work for burning, can anybody help me out.

Sorry about the print screen attachment, its not very clear. Anyway i can make that better aswell.
