HDCP Issue with Contour 6

I just upgraded my DVR box to the Contour 6 today. 

The Contour 6 is hooked up to my Sony receiver which then passes the signal to my HD TV, all by HDMI.

Every time I turn on my TV, Receiver, Cable box I only get sound and then get a quick message about my display not being compatible with HDCP and then the picture goes black. If I change the input on my receiver to something different and back to the input which the cable box is connected then I get my picture back.

Does anyone know how to fix this? It is really annoying to have to go through this ritual every time I turn on my TV.
