How do I create a DVD that retains the Closed Captioning of the source file? The source file is an MPEG-2 Program file (m2p). I have DVD Studio Pro, but it apparently can’t handle m2p files. I may have the ability to purchase new software, so any suggestions on the best program to use would be most helpful. Or, is there a way to create this DVD with DVD Studio Pro, using a different format source file?
