If you have a lcd tv made after 2005 that has a QAM tuner built in and have cable provider that provides tv and internet. You can take your cable plug it right into your tv and receive all your local channels in hd. I only have cable internet service and with my samsung with QAM tuner I get about 15 channels and 30 music channels for free. Its FCC law that any channel you can receive free with antenna they cannot scramble and comes through your cable. Plus you get smooth hd with no skips hehe. You have to have internet service atleast or basic cable for this to work, and its not available in all places I'm sure.
Already tried that route and I can only get the PPV channels. If anyone around orders a movie it'll come in, but not the local stuff. Local here is actually from about 80-100 miles away, so that might make a difference. We had been with satellite for many years (cable wasn't an option) but after doing the Nielson thing I started to wonder why I was paying $100 a month when we only watched 3 channels. PBS, CBS and Discovery. Two of which we watched on the antenna. So I pulled the plug and nobody even noticed for 2 months. When we moved and cable was available, I went for the internet and said forget it to the rest. $80/mnth for basic.
It's not just us that lost the locals, but a big portion of town, so maybe it'll get better. Until then, I hooked a slingbox up at a relatives house in another bigger town and all our PCs also display on the TVs. So the kids and DH can still get their PBS fix.
Most we've gone without power was 2.5 wks. I could've easily seen DH deciding the TV was more important on the generator before the DTV switch. Now, not so much. So I guess that's +1 for the switch.
Myself, with kids' homework, activities, etc. I could never watch anything when it originally airs anyways, so if I want to watch something I just go to the respective site after the kids are in bed and watch it.
