Hi, I have the same problem too, tried with two different DVD-rom, but still not working. I hope someone can give us an answer to this issue, because I'm very frustrated right now, please someone.
I get this error when I try to include a menu when burning the DVD. I have also found that using the preset menus also creates other errors. I no longer use them.
I see I'm not the only one with the:(Internal error while processing problem). I have several other video programs that are very user friendly. I like to have different effects at my disposal, but I don't understand why a technical team is not readily available to help instead of having to wait forever for a customer to help another customer solve their problem. Does this makes since?
