Please, what do you mean by "select down?"
I tried that and the HDMI 2 goes on and I have to turn off the TV and turn back on and use the TV's remote to get rid of that HDMI1, HDMI1, etc. screnn.
Also, what do you mean by "holding select and system down?"
It seems when I try to do one of the things you mention, the DVD goes on and then another screen pops up that says HDMI was changed from HDMI1 to HDMI2 (the one the DVD is connected to). I then have to get the TV's remote to get rid of that screen with the HDMI1 and HDMI2 showing on it).
This is very confusing for me as it is something new to me and I am unfamiliar with all of it.
This is picture of my TW remote:
I believe you can click on it to make it larger.
