downloaded "hb pc" and "humviewer" to my pc, now how do I record an video from a screen view? I tried today but had to go to the recording view and then turn recording on...is that the only way to do it? Seems difficult to go to one screen, turn on recording, go back to screen you want to record, etc. also, what is the time expected on a recording with a 4gb sd? I feel slightly overwhelmed with this, help. Thanks. Dennis
