As of today, Triangle area Time Warner Cable digital cable customers should notice some changes when they sit down to watch their favorite shows -- an upgraded on-screen viewing guide.

The upgrade took place automatically overnight last night.

Time Warner Cable says the upgrade will make it easier for customers to search for On Demand content or use digital TV features like Start Over, which lets you start a program over at the beginning, and Look Back, which lets you go back three days to watch a program you missed but didn't record.

Other upgrades: The "A" button on the remote now brings up "Find Channels," which lets you find channels by category (sports, news, movies, etc); the "B" button still calls up the search function, but TWC says the search screen is now more intuitive.

For more information about the new guide, visit the Time Warner Cable site.
