Have had Contour 2 (X1-A & XiD-P boxes w/voice control remote) for two months. Shortcomings I've seen compared with the old Contour (Cisco boxes):
1. As above, can't set skipped channels. Sorry Becky K, setting favorites in the Guide is NOT a solution. This makes the channel up/down buttons useless - I do not want to toggle through the 800 or so channels not in my package or I don't watch. In other words, you can't "surf" with Contour 2.
2. Remote only supports Cox boxes and a TV. No DVD, external audio (who uses the tinny TV speakers?), Roku, etc. The old Contour remote supported all of these. Because of that I use Logitech Harmony remotes for both of my TV setups. Sorry Cox, can't use your voice control without juggling two remotes.
3. No "DVR List" button on remote (i.e. go direct to recordings) that Contour (1) had. It now requires 4 button presses stepping through the Contour menu to get to your recordings. Poor UI design. (See above - I can't use voice control).
For what it's worth the new Arris DVR is WAY more reliable and bug-free than the awful Cisco DVR (aka "Reboot Weekly/Service Call Quarterly" DVR).
