Thankfully, my DVR uses the Rovi software. At the moment I have 892 skipped channels. When Cox adds a channel to their lineup it shows up in the guide. Invariably, if I check it out, I get the splash screen that says, "To subscribe to this channel call 1-800...", and into the skipped basket it goes.
Not having the skipped channels feature in Contour is not an oversight by Cox. That's not something you just forget to include. Nor are they working to implement it. It is a marketing decision pure and simple.
How would you know you could be watching the Ice Fishing Channel right now, for an added monthly fee of course, if it wasn't listed in your guide?
