With the program DVD LAB PRO I tried te make te DVD containing 4 programs. One of the programs was a small piece of Korperwelt. The others were programs taken from television. When compiling the DVD I got the message: pre verification fails. What should I do? Is it possible that the piece of Korperwelt is restricted? That it is forbidden to edit. Ik go the piece by using DVD-shrink.
I've never seen that error message before, but are you sure your input files are DVD compliant MPEG. If they're not, then dvdlab will not handle them.
