Just a few observations from wandering the floor of the 2007 National Association of Broadcasters convention. The camera work is really quite suspect in some places... I didn't take a tripod so it is all hand-held. Major shaky-cam in some places.
And as always... the Vox Flash engine is a bit rudimentary so it is often helpful to click play, click pause, count to 10 and click play again. I think they have their frame buffer set to zero, and that means lame playback.
