Had a new install Monday.. 2 HWS, 1 Joey. Last night, my daughter had been watching Cartoon Network.. I changed the channel to our local ABC affiliate live TV (on this DVR PTAT is disabled, and the DVR wasn't recording anything. Decided to mess around with the PIP for the first time... All worked well.... returned to live TV, ABC. Went into DVR, selected the other Hopper WS where PTAT is enabled and started playback of a show from Tuesday night. Video was from Cartoon Network live feed, with no audio...... Thought maybe I made a mistake.. went back to the DVR menu, into PTAT, selected show to watch, hit start over. Video was from Cartoon Network (live feed) and audio was from DVR PTAT playback... Stumped.. I excited payback and returned to live TV... it went to my ABC broadcast. Red Button checked tuners.. only ABC listed. Started PIP again... ABC on main, Cartoon Network on PIP.. Exited again to live tv... DVR'd back to other HWS, went to PB show, and again, picture from Cartoon, audio from DVR PTAT show.. Hit PIP, and as normal behavior, no PIP.. Exited back to Live TV. Power cycled HWS.. no red button. After that, all worked well. Today I had an issue with the Joey saying it had no broadband connection.... after many tries, and a couple of other setting flips, it worked as normal and On Demand started working again... Hope these issues are not SOP for this system..
