In the meantime, I find that if I set my video monitor at "Normal" on a cheap HD TV i bought a while back, when the camera begins recording, I do get a relatively decent aspect ration representations. You should test out different configurations with you chosen video monitor, to see which on works best for you.

Thanks much - for both the answer and all the awesome work you're doing. Your ML is about to make a bit of money for the folk at Small HD.

I've been looking into the Marshall, Ikan and a few others, and Small HD seems to have the best price/feature/quality ratio. The Marshall was a close second - largely based on viewing angle.

And thanks, Chris, for the advice. I've not had my hands on it, but I think the Small HD DP1 will be good for not only my 5DM2, but also general usage with my XL-H1 or my potential future camera of the Sony EX1 (if I can ever justify the expense).

Thanks again.
