Not with newer tv'sDo you get the box saying "HDMI connection not permitted"? Also, it is odd, but I have to change the HDMI input in order to watch the slingbox. My Tivo is connected to my Xbox via HDMI 1. If I have my TV on that input I get the error "The connected video signal is not supported". But if I change the input to HDMI 4 I get the picture, but that 'not permitted' box appears. This never happened before.
