Metheor got about something like 16M $ in funding, if I remember good, and they can't afford a proper microphone for the speaker? :)
We do try to improve AV with every Devshop, and we have recently started to bring in AV professionals to help. But honestly, pre-1.0, I think it's way more appropriate for us to be spending our time and money on advancing the framework than on super slick video presentations. In many ways it's more like the Meteor community's time and money.
