Here is a fresh paste from my test machine: https://pastebin.com/ec0wns6J  This is with -v record,playback --loglevel debug.  If anyone has any suggestions on more things to make verbose, I'm happy to oblige.  I'd like to figure this out.

I fixed the config.xml error from the last paste but that wasn't making a difference anyway -- I was able to watch live tv with that misconfigured.  It's fixed now.  BE and FE are on the same machine and the HDHomerun Prime is connected to my router.  I shut down my regular backend just in case.

I can tune in most channels until the "premium" ones.  By premium, I mean encrypted but with cci flags free to copy away (as I can do with my F27 backend presently on these channels, like USA HD, AMC HD, etc.).  When I switch to a "premium" channel, mythbackend freezes and gives the errors shown in the log.

I was using the schedules direct xml grabber, which is working fine in F27.  I switched it to the regular Schedules Direct grabber on this test machine just in case it was a channel issue, but I really don't think this is the case since the F27 box works perfectly well as-is.

Thanks for any input!

I dont use HDHomerun Prime, Fedora or Schedules Direct so I can't help much. But personally I would be doing a line-by-line compare of the tuning section between your F27 install and the F28 install. This part (following), but specifically what does the F27 install show after reading the program map section. The F28 install aborts immediately after that part.

What are the compile options on the F28 install (mythbackend --version)?
