@Scherrman you have really helped me out. I didn't understand that the Joeys are really just a dumb terminal to the Hopper. By stating "joining" I realized that you are mirroring what's on the main TV (like the TV2 output). The hopper in essence "owns" all the content, whether it's live or recorded. The joeys can do four things if I understand you correctly
1. Watch any recording independent of what the main TV is doing or any other joey is doing
2. Watch the same thing the hopper is showing/viewing
3. Watch PTAT (in essence watching what's live from the PTAT tuner)
4. Swap to an open tuner to watch something else
What can't happen (which is why I need two Hoppers) is that in a 1H/3J scenario, one joey HAS to watch the same thing that either the hopper is watching, another joey is watching, or recorded content. You can never have 4 different live channels in that scenario (until OTA comes). We frequently have this scenario at prime-time at my house (where all four TV's are watching something different, but typically all prime time shows).
Can you clarify PTAT in this respect? One of the earlier Q&A's stated that the H/J system can have up to 6 viewing tuners with PTAT. So with PTAT, could the 1H/3J be actually watching 4 different sources (as long as two of the Joeys were watching PTAT?).
Is PTAT treated like a DVR recording in that case (and technically not live)? In my scenario earlier, let's pick tonight at 8pm. Hopper is showing "The Middle", Joey Kitchen is watching "Am Idol", Joey basement is watching "Cold Case" and Joey bedroom is watching One Tree Hill (not PTAT). Will this work or does Joey bedroom have to watch the Hopper, kitchen or basement channels?
Thanks again for your input.
