I have tried three different VCRs...the VCRs work great (can watch movies, ect) but cannot get picture or sound from dish thru VCR tuner. I have the 522 and tv1 works great thru VCR. This is a recent install...I looked at the wiring and it looks like the main drop is coming in thru a splitter and then into tv1 / tv2. TV1 then has a direct line out. TV2 comes out and connects back into the splitter, and then presumably into the wall and downstairs to the second tv. Any ideas? Will a line amplifier help? Thanks.
