Got the 9.1 update a few days ago, on both the S3 and Toshivo SD-H400. When I got home from work tonight my wife informed me the s3 was broke. Any button press on the remote except for TV functions, resulted in a "bonk" sound. Only volume up/down, and tv input worked. Tivo was displaying one of the two live tv items it was recording. No guide, or position bar at the bottom of the screen. Pause etc. did nothing but "bonk". I finally pressed the clear button and it I didn't get the "bonk" sound for a few button presses, and then it came back. I suspect there was a menu or message that was requesting input, but was not displayed. Tried to enter 911 clear but just got more "bonk". Pulled the power cord and waited for it to reboot. Seem to work OK for at least another hour, and came upstairs to bed. S3 has two cable cards on Comcast.
