That's quite likely, as my original 3 LLB HD DVR would pass HDMI though my switcher. This had to be replaced by a 5LLB unit. The three LLB roof units kept filling up with water and failing, because they were not properly sealed. Yes, another case of Far Eastern Junk manufacture. The New Direct TV, will not connect to the TV via the HDMI switcher. I have it connected though component video, and that's the way it will stay. A pox on the lot of them, and especially this HDCP nonsense.
