The update seems to have made my no-audio problems worse. The only 2 devices I have connected to the 970 is a Denon DVD player, & a Prismiq MediaPlayer that I use to stream Internet audio. I'd guess 3 out of 5 times when I play a DVD or stream web radio, all I get is silence. I can see the song counter progressing on the player, but nothing from the 970. The ONLY way for me to get audio is:

1. get up & turn 970 off then back on
2. switch to radio input then back to device input

While I'm impressed with the overall build quality of the 970, these software bugs have no place in a device of this price class.
