I get this on a WD Live box when running through a (cheap) autoselecting HDMI switch. It's got to do with the switch borking the digital handshake. The switch I use has a remote for manual selection.. If I switch to the WD input from something else (automatically or maunally), I get a pink screen, but if I press that input number a second time, it renegotiates the connection and it works fine (only the WD Live box does it regardless of what port it's on, not the D* receiver or bluray). If your switch has a remote, try that. Also might try not powering on the D* receiver until after you've switched the switch.
