Within the context of channels that are included in my plan, I'd like to see a view where all of the HD channels, PLUS only the SD channels that re not available in HD are shown. In other words, everything that's available to me WITHOUT showing the SD and HD duplicates of the SAME channels. From there it would be easy to make a custom "favorites" view, eliminating the shopping channels, infomercial channels, and non-English speaking channels, etc., that are of no interest.
I do see that it makes some sense for Xfinity to group channels within certain genres like News and Sports in close proximity to one and other. It's the SD/HD duplication that clutters up the guide.
If the favorites guide would just use the channel number for the selection it would prevent duplication all together. Seems like a simple fix just program it that way. That is what other cable provides do. Keep it simple theory is what I like.
