Not a matrix switch, but when I power up my system, it defaults to the DirecTV box as that is what is used 95% of the time. It is running into a Denon X5200 and then to an Epson 8350.

When I switch the input to a BR or ATV and then back to the DirecTV box, I get no picture. I have to manually power cycle the Genie (HR54) to get the picture back. This just started happening in the last week or so and while not a matrix switch, a similar issue.

So this weekend I am going to reprogram my MX-890 to power off the Genie when I switch inputs and power back on when I return to DirecTV. Kind of a pain, but less so than getting up and going to the rack.
