But the audio quality is poor. It seems like when someone high profile (like MIT TechTV) goes to the effort of recording and posting video, they could spend a few more bucks and put a microphone on the speaker (or hook in to whatever audio system that handheld mic was hooked up to).
As a general rule, using the build in mic of a video camera at the back of a room will yield tolerable audio only in very rare conditions (a room that's "dead" acoustically, and a very quiet or nonexistent audience).
