Relentless, have you tried turning the TV off and back on? I'm curious to see it power-cycling devices other than the 990 makes a difference.

Ritz, I was under the impression that the 990's switching was designed to be an HDCP-compliant switcher. For most users, it seems to "play nice" with HDCP. I wonder if your cable box's HDCP support is a bit off; I know mine is to at least a degree, and when I was researching HD boxes back in early 2004 it seemed that cable boxes often had a hard time doing HDCP exactly right.
