LOL, Harley ... I think it failed to write straight to a disc from Premier Pro because you need to be a registered user!!!!!!!!!!!!! ooops, now I have spilled the beans! So have to write to hard drive and then burn to DVD. It's a very slow process though ... I'm using a Jack Rabbit burner and the fifteen minute piece I just finished is taking an hour to burn. But once the first one is done, I can copy it in around five minutes. It really is time for a new computer with more power, a built in DVD writer and a HUGE hard disc.
I still can't figure out why the rendering file is 3gb and the burn disc is 0.5gb.
