said by cypherstream:But it does do Auto-HD from what I saw. Like the channels in the 800's or 1000's wouldn't really be needed because if you type in '10' it will show it in HD if available.
That's a major plus, most people I know (especially older folks) don't even know/care/can't remember the HD channel equivalent, and so end up watching the SD version.
I still think it's crazy that more TV providers haven't just adopted the model that Dish has where the channels are literally the same number, so you won't get confused and/or forget the HD version's number. Their boxes tune to the correct version given your set-top box capabilities and/or TV setup preferences on the box.
With everything on Comcast's network being digital now anyway all the "channels" are in a virtual channel table map anyway, so it's entirely arbitrary what number is used in the guide.
