It's that time of year again. A nip in the air. The trees changing color. Well, OK, September is a bit early for either of those annual events, and in any case we rarely experience them in LA, but you get the idea. Fall is coming, and with it thoughts of new high definition programs, new formats, new video displays, new audio gear, and all that other indoor stuff that was pushed into the background by beaches, barbecues, and way too much of that unhealthy fresh air and sunshine.
