Navigating within the Program Guide on Contour is worst than Rovi. With the Rovi guide, you could use the A key to jump ahead 100 channels per click. With the Contour guide, you can only jump ahead 4 channels.
Contour also dropped the ability to "direct dial" into a specific on-demand directory. For example, with Rovi, I could press 2-9-0-3 to directly dial into the directory for HBO/Series HD/Series D-E. I'd rather direct dial than navigate or speak.
Last Channel. With the Rovi remote, you could press one key to return to the last-viewed channel. With the Contour remote, you have to press at least 3 keys to return to the last channel. Somebody should have included a simple Last channel button on the remote.
Closed Captioning. There is also no simple key...or at least non-functioning key...to launch CC on the Contour remote.
HDMI-2, -3, etc. I still haven't figured the TV Input button on the remote. It launches the screen to select another video input to my TV, but the Up and Down arrows on the Contour remote don't allow you to move up or down to select anything. Perhaps another user has figured it.
TV Caller ID. If my Cox phone service worked, I could review the Caller ID with Contour. However, it seems to have limited preferences: either on or off. The following options are no longer available: changing the banner duration and viewing your Call History Log.
Image Resolution. My TV has a feature to display the resolution of the current program. For example, with Rovi, I could press the TV button and then the Info button on the remote to display the current image resolution (720p, 1080i, etc). I can no longer launch this feature with the Contour remote.
It seems Voice Control has replaced a lot of the useful features of Rovi; however, Voice Control is a disturbance...especially to those wanting to "rest" their eyes before starting some yard work.
