Greg is having a problem with HD and Dish Network. Leo says it's probably copy protection called HDCP, and if one thing in the chain isn't HDCP compliant, you'll get an error. Chances are, it's your cables. Make sure they are HDCP compliant. According to Satellite Guys, there was a firmware update on the DISH box that is causing intermittent HDCP errors. Here's a tech note about it. An HDMI splitter can also bypass the HDCP copy protection. It's a common way that pirates bypass this nonsense. If it was Leo, he'd give up on DISH and do something else.
