Thanks Rxx, I'm thinking along thosw lines. You're right that the 32GB limit is an internal, and that a 2nd cam will be the smoothest answer - quick changeover - and doesn't involve having my laptop on the scene. This particular camera also takes an SD card, but the 32 GB card I have appears to be too slow to record on full HD. Maybe one of these faster new generation cards will work on full HD. Just trying to think of cheaper alternatives.
