What is the quickest way to render HDV fullsceen to make a DVD in fullscreen format. No editing no cuts, just 53 minutes of video off the hardrive.

I am using vegas Pro 8 and DVD PRO 4.5

Could you be a little more specific about what format your eventual disc will be i.e. is it DV Widescreen, Blu-Ray or what?

If it's DV Widescreen I'd reckon just use DVD Architect and start a new single movie project, browse for file and follow the make DVD prompts.
