If you're having trouble finding some of your favorite Time Warner Cable On Demand shows, it's because the HD Showcase On Demand channel has disappeared and the content redistributed to other On Demand channels.

So while you may not see "HD Showcase" in your menu, you can still get the same shows on demand in other locations.

TWC has advertised the changes on Channel 100 and in crawls on the Weather Channel.

Here's the full list of where the Showcase On Demand content has gone:

Exciting news (for me, anyway): Time Warner Cable intoduced its iPhone app today.

The app is essentially the same as the TWC app that has already been available for the iPad, it's just that now it works on the phone.

Just install the app -- TWC TV -- from the App Store, and if you've already created an online TWC account (to pay bills or access online content or DVR management), sign in and you're ready to go.

I just took it for a spin and it works pretty well. It certainly looks nice. As with the iPad app, you have to be at home on your home network to watch live television content. But you can look at a television guide and manage the programs on your DVR, including setting new programs to record, from anywhere.

The C-Span Campaign 2012 Bus will be in downtown Raleigh on Monday with special programs highlighting Martin Luther King Jr. and the Civil Rights Movement.

The bus, which will open to the public at 9:30 a.m. on Edenton Street near the capital, comes to Raleigh as part of C-SPAN's "Road to the White House" tour. It will move at 10:45 a.m. and reopen at 11 next to the Progress Energy Center for the Performing Arts at the Corner of Wilmington Street and South Street.

Visitors will be able to access information both inside and outside the bus on HD TVs, touch screen computers, laptops, and mobile devices. The content will consist of archival clips and historical programming focusing on Dr. King and the Civil Rights Movement.

Time Warner Cable announced yesterday a new app for Android tablet customers that gives them the ability to program their DVR, add favorite channels and use their tablet as a remote control.

The Time Warner Cable press release said the app is available to all customers with set-top boxes or DVRs running the Time Warner Cable “Navigator” interactive program guide.

The app is designed to run on any Honeycomb (Android 3.x) tablet and is certified to run on the Samsung Galaxy Tab 10.1 or Motorola Xoom. Customers can get the TWC TV 1.0 from the Android Market and log in to their TWC account from there.

Time Warner Cable introduced an iPad app in March of 2011 that lets TWC customers stream TV shows over their iPad. 

First of all, nobody panic...

If you're watching television or listening to the radio tomorrow at 2 p.m., you'll experience a 30-second test of the Emergency Alert System (EAS) that on the surface will seem like every other EAS test you've ever suffered through, except for the first time, Wednesday's test will be broadcast nationwide.

The test is a joint effort by the FCC, the Department of Homeland Security, and the National Oceanic and Atmospheric Administration. According to the FCC, the purpose of the test is to assess the reliability and effectiveness of the EAS as a way to alert the public of national emergencies.

Just got this press release from Time Warner Cable, and I know it is going to thrill some of our weather-obsessed readers:

Beginning November 3, digital customers across North Carolina and South Carolina can watch the following channels in high definition:

•       The Weather Channel HD-channel 1418
•       G4 HD-channel 1311
•       Cooking Channel HD-channel 1353
•       DIY  HD-channel 1356
•       FEARnet HD-channel 1644

A small Raleigh company that makes digital antennas wants to encourage TV fans to ditch cable and switch to free over-the-air hi-def TV, but the company will not be getting that message out on cable television.

Time Warner Cable notified Raleigh-based Mohu this week that it won't broadcast Mohu's ad for a "Leaf" HDTV antenna. The ad reminds viewers they don't need expensive cable service to watch HD programs.

Mohu had tried to run the ad in two Midwestern markets -- Columbus and Kansas City -- to test viewer response. The Leaf antennas, which cost $44.99 each, are paper-thin and measure about 12 inches square.

"It's our policy not to take ads that directly compete with our broadband, voice and video services," said Keith Poston, noting the policy is well-known with advertisers.

Time Warner Cable plans to lay off 45 employees in Wilmington as the company consolidates operations in the Triangle.

The telecommunications company notified the N.C. Department of Commerce that it expects to lay off 45 call center workers by Dec. 15.

The company said last year it would merge operation in Morrisville; at the time it expected to transfer 100 jobs from the Wilmington call center. 

Time Warner spokesman Keith Poston said about 20 of the Wilmington workers transferred to Morrisville and 50 left the company, leaving the 45 at the call center who will be laid off.

You can always feed your brain while you feed your belly at the fair. That's never been more true than today, when your kids can catch a bunch of interesting science stuff going on all day long at the Time Warner Cable tent.

Things kicked off a little while ago with experiments from NC Science Festival's "Science LIVE!" demonstration. That will happen again at Noon and 1 p.m.

At 11:30 a.m., meteorologists Gary Stephenson and Lee Ringer from News 14 Carolina explain how tornadoes and other weather systems work, and answer weather questions from the kids. They'll do that all over again at 12:30, 1:30, 2:30, and 4:30 p.m.

Another big event today is from FIRST Robotics Competition Team 2059: the Hitchhikers will display their Rockin' Robots with a student-led demonstration. The Hitchhikers are an FRC team from Cary. That happens at 2 p.m. and again at 4 p.m. and 5 p.m.

In between all that (at 3 p.m.), The NC Museum of Natural Sciences will do a presentation on fossils. Kids can see and touch bones, shark teeth, and other prehistoric fossils.

It's all part of Time Warner Cable's "Connect a Million Minds" initiative.

Dean Debnam's television ad designed to help the Democratic school board candidates made the air, but not without some grumbling from the Wake County Republican Party.

Debnam's group, N.C. Futures Action Fund, bought time from Time Warner Cable to air the spot warning about the "tea party takeover of our schools." The Republicans argued the group should have to file a public disclosure statement before it could air the ad.

Broadcasters are required to maintain a file for public inspection showing who has bought political ad time. Time Warner posts the info online here.

But attorneys for the Futures Action Fund argued the paperwork didn't need to be filed because the spot didn't say vote for or against any specific candidates. Keith Poston, a spokesman for Timer Warner, said the broadcaster agreed that it was an issue ad that didn't need to be placed in the public file.
