I live in Southeastern Pennsylvania, in Montgomery County... I spoke with a Comcast Rep this morning on the phone; she was cordial, but when I casually mentioned DVI she didn't know what that was. Fine. She informed me that I could only "rent" the High Definition Set-top box (I was under the mistaken impression you could buy it too) and that it would replace the digital box I have now. The price would be the same as digital cable. She told me all the needed cables come with the box. Six stations are currently available in HD--two are premium channels. Comcast Sportsnet broadcasts some of its sporting events in HD. 1) For those that have the set-top box from Comcast: Can I use my Yamaha receiver to get 5.1 DD audio? 2) If you watch the Regular channels through the hi-def input on Comcast's box, will I be able to stretch the picture on a widescreen set, or will I be stuck with black bars instead of grey for 4:3 programming? I read on other posts that it depends on which box Comcast gives you. The older boxes presented this problem.... 3) How does the Comcast Sportsnet games look in HD and are you concerned about any burn-in issue with the time remaining logo that the games use? Thanks very much.
