This is exactly what I been telling folks but never had the technical pizaaz
to tell the story. I've seen our 720 material side beside on an HD
broadcast from the same station and there is hardly a difference. Thus, it
appears that the whole 1080 is a line of crap since the broadcasters are
compressing the output and thus it's merely a hyped up SD (instead of 600
lines or below. Thus, I guess I can say, we are producing Entry Level HD
:o)
