I am not sure if it was with the 5.8 upgrade or exactly when, but I am noticing different behavior when I try to go between my last 2 channels.
I have a sofabaton remote and I have a button configured that I believe corresponds to a Live TV button. Anyway, it mostly served me as a way I could toggle between my last 2 channels. Today if I use the guide or type in the numbers for a channel it will still do this function. However, if I use the channel up and down buttons it seems to lose what channel it was last on. For example, if I use the guide or type in channel 4 then type channel 5 I can repeatedly hit the button and it will go back and forth between channels 4 and 5. If I am on channel 4 and use the channel up button to go to channel 5 I cannot toggle back and forth. In the very recent past I could do this. And furthermore, if I hit channel up quickly in succession ... lets say from 4 to 7 I could then toggle between 4 and 7.
I know this is not a huge deal and I can live with it, but I certainly liked it better the way it was. Anyone else see this? Anyone else care, lol?
