I am running a bunch of Tivo boxes through a matrix in my home. My problem is that I was running a Tivo EliteXL4 independent of the system to my Home Theater Room over HDMI.
Here is the problem...
I wanted to add the Elite to my matrix (which is a component matrix) and so I added component cables out to the matrix. (HDMI still goes to an AVR and then out to my Home Theater Room) So...I am able to get video and audio everywhere over the component, but when the Pioneer AVR is off... (it feeds the HDMI to my home theater), the picture gets steady glitches about every 7 seconds or so on the component video output.
If I turn the AVR back on... problem solved.
I hope I didn't confuse!
