I did open a support ticket with Tablo. They tried helping by remoting into my Tablo and asking a few questions, but then I got a sort of canned reply about general signal issues (have your antenna high, etc) and they closed my ticket.
I would buy that explanation if I didn’t have 3 TVs and a Simple.TV that all can pull the signal. I’m considering returning the 4-tuner to try a 2-tuner. I see some people have had better luck with reception on the 2-tuner. My TV hooked to the same coax outlet shows 100% signal quality and 84% signal strength. I’ve even bypassed the splitter on the outlet (which should increase signal further) and still no channel in the scan.
Edit: Also, does anyone else know why my channel scan finishes saying it scanned 72/69? I read that as it scanned 72 channels out of 69 channels?
