I have 2 questions. First one is how do you know if your firmware is upgraded? I just bought the 970 2 weeks ago. My assumption is it is updated. But when switching channels or switching sources (ie:video 2>video 3)I sometimes get load pops or at times I will get super low level sound with audio snow (loud) over the audio. I counter this by switching the surround mode.

Second question is on the osd there are 2 lines right and left. On the screen left there is a 2.0 or sometimes a 3/2.0 displayed. What is that? I assumed it was speaker config. but lately I'm not sure becasue sometimes its optical output on audio and it displays 2.0, then other times it is optical output and it displays 3/2.0. What is it?

I love the 970 there are many things I like about this system but the little things start to add up, please help.
