Just got a new HDMI cable to see if it works better than my Monster component cables and when D* is being viewed via the HDMI cable, when the H20 switches resoulutions as the channel changes formats (ex. ESPNHD 720p to HBO HD 1080i), it gives solid signal for maybe 2 seconds then goes black for maybe 4 seconds, then goes back to solid signal for 2 seconds, etc. The only way to stop this from happening is to turn the reciever and TV off and then back on. This doesnt happen all the time, but usually ends up happening eventually during the night. I believe it happens promarily when viewing 1080i. I have a 52" Toshiba DLP. Any ideas as to why this is happening?
