Hi everyone! Welcome to what I hope will help you (and me) if you're considering "cutting the cord" to your cable/satellite/unborn fetus (well, maybe not that far). I have just begun the process as I have received permission from the big boss aka my wife to do so.
My first step last night was to hook up a crappy antenna I had to the existing unused cable outside and run our TV through and see if it picked up anything. And the result was (in my opinion) a resounding success. I grabbed 20 channels, and only 7 of them were church related and/or Spanish speaking! NBC was the only channel that didn't have a good signal. And one nice thing--my Dish receiver allows me to plug the antenna to it and I can switch to the channels through the receiver (no program guide data, though). And I know I was missing 2 other channels that I had picked up earlier using a powered indoor antenna that for some reason didn't come up this time.
Next immediate step: Remove the unused Dish that is on my roof (I recently had the service changed so now I have a single Dish in my front yard--they wouldn't take the other on one my roof down due to covering the screw holes in the roof), and leave the stand and then hook up an antenna to that to see if that fixes the NBC problem (I think it will).
I've also bought "PlayOn", which allows me to stream media from my PC where I store all my media to my TV via my PS3, and has lots of available channels for the networks, DIY, Food Network, NFL, ESPN, Amazon, Netlfix, etc. Just a one-time fee, plus I already have connectivity to Amazon, Netflix, Vudu, and Hulu (among others) on the PS3 itself.
Got the name of a VOIP company from a friend that's using it and is liking it. Stepdad is bringing me his Roku box that he isn't currently using so I can mess with it--I plan on buying one (or two) myself eventually. I also have a blu-ray player in my bedroom that has a bunch of the movie/music services available on it.
The "big" change--switching from DSL to cable. They have to run all new equipment down to my house since we're so far off the road. Also they'll need to add a few new outlets as well. Since I've never had cable, I only have 1 cable on the outside of the house that goes to my living room (which I plugged my OTA antenna into) and that's it. Don't know how they'll handle that. I'm trying to prep everything else in anticipation for that to happen.
I will retain Dish a little longer (due mainly to the update I mentioned above), but eventually will try to get rid of all of it in favor of the internet stuff.
Now, all that being said, any suggestions, bad experiences, good experiences anyone else can give? I will continue to update the thread on my progress.
