@merlin-beedell I checked out the new "Dashboard" Ctrl Alt 8 (Not Ctrl Alt F8 as in manual) but I think not what you want. I use Vegasaur for 1 click render to DVD .iso.
Interesting thing is that if you hover over the "Power User Mode" in the Dashboard the hint says you have all of the powerful features available to you in Vegas Movie Studio? I guess someone overlooked updating the "hint".
This hint should say Vegas Pro.
