So I called Tivo support for the 8th time today to tell them that my problem with the HD channels going blank despite swapping out S3'S, multiple sets of cablecards, hard resetting the Tivo, downloading 9.1, etc., etc., still exists. Because I have apparently tried everything to resolve, my case is now being forwarded to the "CSI Investigators". I am told it will be 3 to 5 days before I am contacted by this new group. Has anyone been down this route before? Have you been contacted by these "investigators" or is this just a cruel joke being played on a hapless S3 owner that just wants his Tivo to work? Don't get me wrong - I love Tivo, and I just want to solve the problem. Maybe this group will actually work with me to find a resolution..... My wife says I am just a hopeless optimist.
