Firstly, record in R3 (720p 60Fps) .. don't bother with 1080p as it's a nightmare to edit.
Secondly, when using in the car, to get interior light use it on standard setting, but for outside light set focus from CNT to SPT so it focuses outside. (actually can't remember which way round it is, so check the instructions)
Thirdly, you need a mega processing lappy if you intend to do lots of editing, at least a 64bit processor with 8gig memory, I use Cyberlink Powerdirector 9.0 - just about to upgrade to 10.0. Great product but it does have a few issues so you need to save regularly, i.e. after every change. 9.0 and 10.0 are for 64bit machines only.
