Why don't I have a channel guide with an over the air DVR?

Episode 1531

Jerry from Hatfield, PA

Jerry has a Dish DVR which can receive over the air signals. He saves the channels and gets no information on programming. Leo says that's because the DVR isn't getting a channel guide in the over the air signal. Channels used to include that data on side ban channels, but they may have stopped doing that and as a result, his DVR can't get the channel guide data. That's why TIVO charges a monthly fee, for a channel guide.

Why is my TV reception so bad?

HDHomeRun Prime

Episode 1422

John from Bay City, MI

John has cut the cord and he's having trouble streaming live sports with an over-the-air antenna. He says that the antenna plugged into the TV is ideal, but the HDHomeRun and Tablo have issues. That points to the culprit, then. Leo says LCDs have issues with live movement and a higher refresh rate will smooth that out. John should look for a higher frame rate in his TV's settings.

Can I get a DVR for my TV antenna?

Tablo 2-Tuner

Episode 1376

Bill from Denver, CO

Bill cut the cable and is now using an antenna again. He'd like a DVR for it, and is wondering about the Tablo 2-Tuner DVR?

If Bill couldn't get over the air television, streaming would be his only real option if he's cutting the cord. But if he's within line of site of stations, Leo says the Silicon Dust HD HomeRun and the Channel Master are his best bets. Leo doesn't know much about the Tablo, and he recommends ChannelMaster, but the Tablo looks OK.

Why did my antenna stop getting one of my channels?

Jill from Los Alamitos, CA

Jill watches TV using an antenna over the roof. Leo says that's the best quality HDTV because it isn't compressed. Suddenly, however, channel 2 (2.1) is missing on her TVs, while her mom still has them. Leo says that Jill is likely on an edge area where it can work, but may not work at other times. She should check out TVFool.com and it will tell her what channels are available in her area. One TV may have a more sensitive tuner than the other, or it could be that less cable is also used, minimizing attenuation.

Episode 1235

Ben from Omaha, NB

Ben watches his TV with an over the air antenna and it occasionally loses signal. Scott says that generally speaking, an OTA antenna inside a home, like an apartment, works best near a window and within line of sight of the transmitter. Scott recommends going to AntennaWeb.org to find out how to maximize his TV reception. He can input his location and it will let him know where to point the antenna. Titan.tv is another source.

Aereo's Individual 'Dime Sized Antennas' Claim Might Not Be True

Television

Episode 1096

The Supreme Court ruled this week that Aereo is no different than a cable company, and should be required to pay retransmission fees. Aereo leases individual dime sized antennas to customers so they can watch local broadcast television for a low monthly fee. But this claim that all of these small antennas work independently from one another could be a lie. It may not technically be possible for such a small antenna to work by itself, and they may instead be working in concert as an array.
