Ok got it now. Thank you very much.
This is a discussion on 720p Video Recording Finally Possible on CM6 within the Nexus One Development & Hacking forums, part of the Nexus One category; Ok got it now. Thank you very much....
Well thanks everyone here. I started today with a stock N1 and now have it rooted, with Cyanogen 6 stable, and One of WildMonk's kernels. (I didn't write down which one I flashed).
I only had to ask 1 stupid question, which didn't really have anything to do with modding the phone. This is a very instructive thread!
Also, there were a couple people looking for a OS X program to determine frames per second. I found this: MediaInfo
Of course it is telling me I'm only getting 12.539fps, but I've done enough for one day.
