Comcast came to setup the new HDTV box for me. Its new to the Boston area. I have a Sony 36" XBR 400 which accepts 1080i, 480p, etc. Basically hdtv ready, though not widescreen. Cable person shows up early, leaving my wife to help (I wasn't home yet). After 20 minutes, with me on the phone, he finally gets the box working. Of course, there isn't any red showing on the screen, and the speakers are buzzing. He had mixed up the red sound and component cables. My wife was able to figure this out. After all that, how does the HDTV look? It looks exactly the same as the rest of the lineup. Flipping between HBO HD and HBO, no difference. Of course, that's when HBO HD is working. The same with ABC and CBS. No differences. The PBS demo channel looks bad as well. Does the cable box need to be configured specially for the HD signal? Is it possible its just not on correctly in my area yet? I'm pretty sure nothing on my tv needs to change. Anyway, anyone with Comcast HD working, how is it, and was it a pain to get running?
