I thought this PJ was HDCP compliant. I connected an M1/DVI cable ( monoprice) from my Cable Box to the PJ. It worked OK for 2 days. Even the switching was greatly improved ( SD to HD etc)

Now I keep getting an error message that says "your display device has been compromised. Use Component connection"

Could this be a problem with the Cable box, or the cable? Strange that it worked OK for two days and now doesn't.

Any Ideas?

Thanks
