Have downloaded a 30 day trial of Corel video pro X4 and everytime I burn a Disc I get "Unspecified error 5.0.0" The disc is burnt but not finalised so I can't play it. I've tried different discs. I've made a video file first (MPEG-2)then dragged it into the timeline, I've downloaded updates, you name it i've done it but still get this error message. Any suggestions Please.
