FWIW I do have pass-thru set to the input to which our HDD-based media player is connected, so that the wife and kids can watch recorded vidoes by simply switching the TV to the secondary HDMI input, and I also have HDMI control enabled for the BRP so that the AVR will automatically switch to the BRP if they wish to watch a disc rather than the media player. Otherwise, when they turn on the TV, it automatically selects the cable box. Sooooo..... the normal sequence of connections is:
Turn TV on, signal is from cable box (only gotcha, remember to turn on cable box!)
Select HDMI2 on TV, source is media player (thru TV speakers unless AVR is on)
Turn on BRP then AVR turns on and BRP is automatically selected
This scheme was the result of not only much thought but also a lot of trial and error.
