I could be wrong....but it sounds to me like a typical HDMI/HDCP handshake issue....
damn protocol...
in my set-up....the DVD player MUST be turned on last...switching sources won't cut it...should I switch sources....when I go back to the dvd player...I must turn it off and on again or else all I get is snow....
