Yes, I will put some RAM on my shopping list and retry. The 'puter was probably doing a lot more disk access in lieu of RAM.
I had challenges, but now that it's been successful, I am really happy with the results. The Blu-ray video looks spectacular. Really smooth and sharp.
Great I can't wait to hear about your updated results with more RAM. My 2.8 Mac Pro is coming in two weeks with it's 8800GT video card and 6GB of RAM (4GB from OWC). Then I'm hoping that NAB will be the launch of new cinema displays (HDCP) along with DVD Studio Pro 4.5 with blu-ray burn support.
