Well good freaking grief.
So I have a Pioneer Elite SC-77. I have the Tivo hooked into a 4 by switch (with my xbox 360 and HD DVD player)...items I don't use as much. For the last, probably 8 months or so It's gone through that switch. No problems. Today it's working around 2:00 PM. I power the unit down to move it, when I power it back up, it won't work. The 360 and HD DVD player will play through that setup, but not the Tivo. After messing around for about 2 1/2 hours, I figure out that for whatever reason, that setup will work on HDMI Inputs 1-4, but it won't on 6-8 (HDMI 5 is a front input)
Any idea why all of a sudden my Tivo won't work on HDMI 6, 7 or 8? I also tried hooking the TIVO directly into the AVR into those inputs without the switch, and still no go.
