I have checked and have not found a similar problem with a solution.
As far as I can tell the HD I inputs on My Vizio Midel D32h-F0 TV has HDCP rating of 1.4 and is 1080 p X 60. During setup I was given the work around to manually set up for 1080 p. I did so and got an OK Menus and Screen Savers Display fine. Any video I try to play generates the DHCP Error 020.
I followed the suggestions about unplugging etc. No joy. What now?
