I have Movie edit pro 12 and I want to burn my video but each time the burner area show No BURNER. I do have a burner but I keep getting a message saying No burner found.
However assuming the computer is relatively modern and the burner is found by other software then the problem may be that MEP is too old to recognise the burner.
You can try updating the Burn routines to the latest version available here, however I am not sure if they will work with MEP12.
