Ok, so i want to get orblive to watch tv anywhere over wifi, but i need some help with the tv tuner part. First, can i still use an analog tuner after this DTV transition (I have Brighthouse, and they automatically provide you with digital tv through cable)? Also, I have a Scientific Atlanta cable box, and the orb site says you need an IR Blaster for it to be compatible. What the hell is an IR Blaster? Lastly, I am looking for a tuner for under 40 bucks that is compatible, can you recommend one?
