[21:12] <qwebirc85990> just upgraded to mythbuntu 16.04, clean install, restored db from backup.  All old recordings are accesible, can watch livetv from tuners, but cannot record.  for example, when on program guide, select pgm, tell it to record, a couple seconds later it says "single record +0 recorder failed"
[21:55] <qwebirc85990>  . . . . of course, now it works.   deleted one capture device, hdhomerun, reinstall - then it would record.  though i'm not sure why this also fixed the other hdhomerun prime.
