Thanks for the quick reply - the addy you provided gave a 404 error, but I loaded the Sep. 26 version and tried it out.
I probably didn't make myself clear in my original question; I'm
not looking for an anamorphic or cropped version, just a 16:9 video using 1920x1080 (i.e. not 1736x976) not-binned 1:1 pixels directly from the sensor, in the standard 8-bit mov format with up to 30 min. recording. (Got an interesting crash using the test version; camera locked, had to remove battery...

)
Am I correct in assuming that this is currently not possible? I see that 2blackbar asked about it 2 days ago, but the current test is a different format, right? I don't want to use any other apps than Final Cut 7...
(Sorry if I'm asking stupid questions, but being away for almost a year, I'm virtually a newbie, again...

)
Here's the crash log:
