Finally able to fet this up and runnung at last yesterday, but when I connect my Panasonic DMR EX77 to either HDMI input, nothing gets through to the TV a Panasonic 37 plasma. If I connect my E Xbox 360 elite, both satellite and aux work, passing the picture to the TV. I have tried different cables, and if I connect the 77 to the tv, it works perfectly. Any thoughts on what to check next, they all seem to work on their own, and the Arcam passes the X box signal through. Thanks for any tips or help.
