A friend of mine and myself are having the same problem. I am using driftwood Mysteron and he is using Cake v 2.1 - and we both get the GH2 hanging up during recording (frame freezes, no buttons react, doesnt shut off, have to remove battery, file is 0 kilobytes). I noticed that Canis Majoris Day was even worse and hung up even more often. Is that problem known?

I have an extrememory sd card 32gb, which never gave me any problems with driftwood up until last month.. he is using some cheap card, but then again, its only cake he's using.

Any help on the matter will be greatly appreciated.
