When I change Activity from my Nvidia Shield to my TiVo it turns everything off. If I then hit help it turns it back on to TiVo, If I'm on TiVo and change to Nvidia it works properly, if I'm on Nvidia and I change to my Blu-Ray player everything works fine. Only that sequence is an issue, I have reset and reinstalled the programming and it still does it. My Nvidia Shield and my TiVo use the same TV input but different receiver inputs. Any suggestions?
