Time Warner here in Austin just loves to duplicate channels in their line-up, and I'm sure they're not the only ones that do it. Not only do we get the analogs below 100 all duplicated in digital on a higher number, but all the HD channels get a number in the hundreds (to group them by genre, i.e. sports in the x00's, news in the y00's, etc) as well as a number in the 1400-1600 range (to group the HD's together).
I guess these groupings are aimed at channel-surfing troglodytes, but the duplication is a PITA when searching for new shows: instead of just one listing for a new program, by default you see two - or even four if it's on a network that has both an SD and an HD feed.
What I'd like to see is a simple means of eliminating these duplicates from Channels I Receive. That could be as simple as allowing us to sort the Channels list by call sign instead of channel number, to allow the user to quickly and easily find the duplicates instead of having to page up and down through the list because they're hundreds apart.
An automated process that would select only one instance of each network (and perhaps even deselect the SD if there's an HD equivalent available) would be even nicer. Perhaps it could even be included as part of Guided Setup.
