Um, I don’t know if this will help you, but some time ago we had Vegas Pro 8.0b locking up when rendering HD, and also whenever we used large still images. Vegas Pro 9 is supposed to have been upgraded ‘under the hood’ to accept much larger files and stills.
I assume Vegas 9 PE means “Platinum Edition” (i.e., studio, not Pro)? I am wondering if it really handles HD on all machines.
Just to troubleshoot, could you download the trial version of Vegas Pro 9, and see if that will render it?
It’s just a thought…and it might be worth what you paid for it.
