We've had our 722 for almost 3 years now using the TV2 remote for our second fed HDTV (via HDMI splitter) in our bedroom, that is roughly 35 feet away. Initially, we had to point the remote in certain directions to get it to work and then found the A/B switch to increase the sensitivity distance. That worked beautifully and we've had no problems...until now. We've swapped the batteries and just cannot find a consistent sweet spot to get the remote to work...extremely frustrating. If I go to the living room and stand right in front of the box, it works perfectly. So, this drives two questions: 1) do I need a new remote or 2) is something wrong with the box/antenna attempting to receive the remote's command at that distance? Nothing has changed in my house (no new walls or anything). I don't really want to spend $15 on a new remote when I don't know if that will solve the problem. Any advice / troubleshooting tips would be much appreciated. Thanks!
