Please forgive I'm still a little new at how channel information is gathered, mapped, and used...
Yes, it remains to be seen how channels can be mapped in seamlessly. I'm also curious how, in fact, it will handle channels that come up as X.y. Let me give you an example:
If I connect my cable up to my Samsung DLP (has all 3 kinds of tuners in it) and scan for channels, I get a whole range of channels. The cable versions of my local broadcast HD channels looks like this: 81.1 (KCPQ / FOX-HD) on my TV. No single listing service I've seen (including comcast's own lists) show this channel as 81.1. Instead it's listed as something like 113.
Furthermore, the built-in TV Guide shows no information for this channel's programming. I've tried every zip code and choice I can make in the TV.
Is this going to complicate things somewhat?
