Trouble with playing OTA HD recordings
Hi everyone. I have 5 Apple TVs (2nd and 3rd generation) scattered throughout the house that I'd been using with iTunes but want to migrate to Plex. I also recently got a HDHomeRun Extend for OTA reception, and am using Plex for Live TV & DVR. The Plex server is installed on my Synology RS2416+ (with Intel Atom C2538, so not a terrible CPU as Synologies go). First off, the Plex installation itself seems to be working well - using the Plex app on my Mac, I can view archived movies or recently recorded OTA TV shows. And from within the Plex app, I can view the original format or transcoded formats on the fly.
But I'm having trouble with the Apple TVs. I installed PlexConnect on the Synology (V0.5-18, installed manually from the spk file hosted at brigittehelsen.be/plexconnect). The movies I've archived play back just fine (H.264 in m4v containers, compressed specifically to be compatible with what Apple TVs can handle). But the OTA recordings from the HDHomeRun won't play back - instead I get "An error occurred loading this content". It comes up right away, without seemingly trying too hard. I've also tried playing with the "Transcoder Action" and "Transcoder Quality" settings on the Apple TVs and I haven't seen any difference in behaviour.
I've tried changing the HDHomeRun Extend settings in the Plex app to even Medium quality (480p) so they shouldn't need to be transcoded for the Apple TVs, but no luck. But even with that said, the Synology is able to keep up fine with transcoding when I play via the Mac Plex app, so transcoding shouldn't be the issue.
I've tried the Apple TVs both wireless and wired directly to my router, with the same result.
Interestingly, one of my Apple TVs, for some unknown reason, does seem to work in playing back OTA recorded TV content. But I can't figure for the life of me what is different - it is a 3rd generation, identical to two other 3rd generations that don't work, and I've checked every aspect of its configuration and can't see anything different.
In any event, the plan is to use Plex with my HDHomeRun streaming to my Apple TVs to be able to "cut the cord" with our satellite provider, but this last part of the puzzle has me stymied. Does anyone have suggestions on what might be causing the "Error occurred loading this content" warning - apparently regardless of the quality setting - I even get the error loading a low resolution recording at 480p and 1.7 Mbps. Of course, the files recorded by Plex from the HdHomeRun are .ts files instead of the .m4v files that the Apple TV seems OK with, so maybe some on the fly preprocessing still has to be done but somehow isn't getting underway.
Thanks for any help!
