I have a 3x1 HDMI switch with a Manhattan 1933 on one port and a WD media player on another port. If the Manhattan has power, even in standby, it won't let the media player take control of the switch automatically. So, I plugged it into the cable box and have it set to cut power to the outlet when the cable box is in standby, so the media player can then take over the switch.
And then there is that old Sadoun 22kHz switch that if you connect it to a port on a DiSEqC switch and then switch to that port, won't relinquish the port to let it switch to another port...
Funny, these switches, eh?:crazy:
