Richard,
You conducted extensive testing in this other thread showing frame rate and ultimately spit out results for different resolutions. I was eagerly hoping you would do the same for your Macbook Pro and publish them for us.
I am interested in knowing how many layers I could run of DV, PhotoJPG, and Apple Intermediate Codec on a Macbook Pro as a single output and then also using a DualHead2Go or TripleHead2Go on a Macbook Pro.
