you're welcome. video recording has been a long difficult road from the massively problematic recording of still camera previews to the comparitively easy ride we have now :-)
ideally i'd be able to change the orientation of the camera, but apparently that's a hardware issue and can't be fixed on the G1/ADP at least. >Hi, > >Jason, thank you. That really helped a lot.
