I put my 970 back into place this am and watched Over the Hedge with no problems. When I turned my 970 on tonight to watch something I was unable to get anything out of it. The volume control would not function on the remote or the unit itself. Switching inputs and even turning the 970 off and on several times did NOTHING! On the unit itself it wouldn't let me change inputs either. Any Ideas?? It will be this weekend before I can try the upgrade again, so for now I guess factory defaults will have to work. At least I got that to work.
