You probably should have actually controlled the audio levels on your online video of the digital switch -- clipped and distorted for the first two parts, and almost inaudibly low for the remaining parts. You should re-encode the files. As for the comment on high definition antennas -- there is no such thing, you don't need a special antenna for high definition, no matter what your dish network guest says (or was that your interviewer -- the audio was low enough that it was hard to be sure who said it). It sounded like you said the digital transmitter was staying on after the transition a couple of times through the segment --- are folks still confusing them?
