OMNI2 in Toronto with HDHomeRun = Black (SOLVED!!)
Thanks to SiliconDust tech support, I have a workaround.
The problem, as I understand it, is that OMNI makes a poor choice (technically not wrong, though clearly not recommended) for the PID for the PCR.
Most stations choose the PID for the PCR to be the same as the PID for the video stream, but OMNI doesn't. Media Centre filters which PIDs get sent from the HDHomeRun to it to minimise network (IP) traffic. Media Centre, however, assumes (another poor choice) that the PCR is on the same PID as the video stream and, therefore, never explicitly asks for it since asking for video PID stream would get the PCR as well if they were on the same PID. Therefore Media Centre gets no PCR and the result is no picture!
The "solution" is a simple workaround. In HDHomeRun setup, instead of specifying the app as Media Centre, specify it as Other: ATSC/QAM. This will configure the HDHR to send ALL data (18Mbps) for the station and not filter by PID. Therefore, without even asking, Media Centre gets the PCR.
Works like a charm and, since I'm on wired e'net, bandwidth is not an issue. I'm a happy camper!!!
Thanks to all who helped. Hope this helps someone else.
