I tried several times with different exposures and lenses, same result. So then I did a clean reinstall of firmware 1.0, same problem, likewise with firmware 1.11 and finally back to 3.64 with one check box marked against AVCHD for increase bit rate to 44. I went carefully through the entire process twice with all the firmwares, uninstalling and reinstalling so cannot figure out what happened.

I note that both 24H and 24L in cinema mode came out the same - 10-11 mbps. (Should be respectively 24 and 17 according to the manual.) On the last try after the second reinstall I got 15 mbps on cinema 24H and 12 mbps on HBR mode. The camera is a week old, working fine, the footage looks OK, so is there something I am missing with the camera settings or interpretation of the data?

I noted in another post somewhere here (cannot find it now) that someone else had a similar problem but managed to retrieve the bitrate after reverting to firmware 1.0. I am not sure if they did that working with V1.0 and 3.64 or just reverted to the factory settings of V1.0.

What should I do? Thanks in advance.
