In WMC I am only getting the channels that also go OTA, like ABC, NBC, etc. The cable channels are just black screens.

Once in a while this error pops up: The PlayReady update was incomplete. You will not be able to watch or record protected content until the update is successful.

But immediately after clicking update it fails, asks to try again, and gets stuck in this pattern.

How can I update PlayReady?

Try installing the PlayReady Runtime 1.3.1 manually from here.
