Hello I am having problems connecting my Dish Network ViP 722 to receiver to an HD Leeza using an HDMI to DVI cable. The Leeza is connected to my Optoma projector with another DVI to HDMI cable. The HD Leeza says "No source found". When I connect the 722 directly to my projector instead of through the Leeza it works fine. Also I have an old HD DirecTivo that works fine if I connect it through the Leeza using the same cables. Does anyone have any clue what may be wrong and how to fix it? Thank you.
