I mentioned the other day that ever since L7.50 was downloaded, my 722k would lock all of the HD channels to stretched-out SD. The Mode button on the remote was frozen so I couldn't get the aspect ratio to come back to normal. At the time, all I could think of doing was a cold reboot. That solved the problem for me. Today, I was able to recreate the problem and that's why I've started this thread. Today, I put the 722k in interactive mode to check on the weather. When I came out of it, all of my HD channels were locked in SD just like the other day. After fiddling around with it and confirming that my Mode switch didn't do anything, I went back to the interactive app. When I came out of it, the correct aspect ratio on all of my HD channels was back. It actually acted like a toggle switch of sorts.
