OK, not much help however…
Playing with the camera fo a couple of hours, trying all sorts of things, trying to download new drivers (without sucsess) etc. etc. It all started working! Can’t say what made it work ‘cos I didn’t really do anything different.
The only thing I may have done is play with the camera, taking different videos, deleting videos, turning it on and off etc. Maybe some combination of power cycling initalised it so it worked, I really don’t know.
I will say the software is not good. It works but is rather cluncky looks like it was orignaly written for a 386 pc running win 3.11 in one of the pre-visual basic languages or the like. If anyone ever finds a nicer version please let me know.
Now going off to lighten the launch vehicle.
