Last night the PG showed the Apprentice as being HD with the symbol on the info bar but the show wasn't HD. Am I wrong in thinking that "High Definition" requires, besides the resolution, 16:9 aspect ratio. Granted the PQ from my local digital NBC broadcast was of very high resolution, but it was 4:3. Does anyone know if the broadcasters sometimes send out a higher resolution picture on their digital signals? I know that digital OTA is pretty sharp already but there was a pretty big difference in PQ between the show and the commercials. Did anyone else notice this?
