Anyone do a controlled full-burn battery test in movie mode... just to know what your camera/battery will do?

I was just wondering what movie times people are getting out of a fresh set of batteries. (I do understand that most camera's individual movies will be limited by card/file size and/or record time.)

So how much total time can you expect in movie mode from fresh batteries? Ballpark would be fine.

If you can, please mention: camera, battery type (eg, proprietary, AA, Li-ion, NiMh), quoted mAh, move recording size (eg. 640x480) and speed (eg. 30, 15fps).

Thanks
