So, 4,000 tutorials, and dozens of videos
don't satisfy your need for content, there's another source open 24/7 and it's as close as your TV. You probably haven't tuned to channel 1 since you got DIRECTV service installed (and maybe even not then.) But you know, once you get past the strange fact that it's 100% standard definition, you'll find there's a lot of stuff there you might not know (unless, as I'm sure you are, you're a devoted blog reader.)
From the point of view of you, my faithful DIRECTV experts, there might be something to learn, but it's even better if you are just starting out with DIRECTV. Here's what I do, and I recommend all of you do the same... when a friend calls you up with a DIRECTV problem (come on, I'm not the only person this happens to) you tell him you'll come over and share a beverage of your choice, and in the mean time you have him tune to channel one and check out The Solid Signal Blog on his smartphone. There's every possibility that by the time you get there, you'll find that he's actually solved the problem and then that just leaves social time with you and your friend. That's much better than time spent rewiring someone else's house.
And you know, personally I spent about half an hour watching the channel while I was preparing this story, and no, I didn't find out something new, but I thought it was entertaining and well presented. Now they just need to do it in high definition.
