Hopefully a quick question. I'm hookin up the modulated output of a 625, and I'm wondering if the TV1 signal (channel 3 or 4) is included on the "home distribution" output of a 625, or do I have to use a splitter to combine the channel 3 and distribution output? I know on my 622, both TV1 & TV2 are sent out over the distribution outlet, but on the 625, I'm not seeing the TV1 output, just TV2.
