and a wild one at that, is it the battery that's overheating? If so, I would suggest changing that for a recognised manufacturer recommended replacement as soon as possible.
Not to be alarmist, but we have seen, as recently as last week, and certainly over the last few years, where laptop batteries have caught fire or have other potential hazards, last weeks example, HP Notebook PC Battery Pack Replacement Program.
In the past that was where users replaced batteries with cheaper, non-recommended batteries.
Yours is not a laptop of course, but it makes me wonder.
Also, make sure any air vents are not blocked.

While filming some videos using this camera, it has a tendency to overheat and shut down. Have others had this experience? What's the solution?
