I'm getting some weird problem powering on and off the tv and switching inputs but once the tv is on and on the righ input control of smartTV apps like Netflix or Amazon have no problems. Pause and FF or Reverse is instantaneous so I don't think it's a IR problem. The X1 hub is in direct line of sight and 5-6' away from tv.
Also OPPO-UDP-203 Blu-ray player has an X1 IR blaster with 2" of sensor and no response form X1 control. OPPO remote works fine
updated X1 hub and remote to latest firmware and am using the lates OS SofaBaton app
