Just out of curiosity, does the family ever complain about any hit on their network? Do they have like a spare TV they connect it to so you can control which channel you view? I tried this once with my brother but he started whining about it sucking up his bandwidth.
I did the same thing - am loving saving the $100 hit every month, and find I don't really miss it with free HD OTA. I did however pay for the digital Sunday Ticket since I somehow qualified, so I will be streaming this year and use Airplay to watch on the big screen. That's all I really needed DirecTV for, and now I can get the Sunday Ticket without having to pay their monthly ransom! I'm a little nervous about performance, but when I had ST Max in the past it seemed to work well, I just never really solely relied on it.
