[minefield]

Hi All,

I'm new to this fourm , Here's my problem,
I have sony vegas and sony architect studio , I have edited my project on vegas and then it is transfured to architect studio for burning, Thats where my problem started, It seemed to go ok.
I clicked on make a dvd
then on burn
left it on prepared current project
gave it a name
then burn
as I was getting ready to put a blank dvd in it started burning with no dvd in it even asked if I wanted a second copy burnt .
Anyone know where I have gone wrong
need help
