Hey Tommunist. Thanks for the info.
Is the iTunes download one file (the feature) and the commentary as another (video and audio) file?
Do you have to download both? Or can you choose?
Well, perhaps because of the Apple news today, redeeming was a little wonky. However, with the code entered, two downloads occured, the regular feature, and the "enhanced commentary" download. I suppose you could stop the feature download if you didn't want it; you should have the option of re-downloading it later.
I didn't have time to actually view the enhanced commentary yet! But that's the single most-wanted feature I'd want on a Blu-ray!
