For anyone who is seeing this problem, and you can add me to that list, note that a ticket was opened and apparently quickly closed in the Kodi bug tracker. Apparently the Kodi developers don't seem to think it's their problem:

"negge" posted this:
It is very likely that it's due to some changes in the addon between Helix and Isengard, if so you can open a ticket at https://github.com/kodi-pvr/pvr.hts/issues instead (please attach the debug log I requested if you do).
IMHO when a developer asks for a debug log he's waving away the problem, because he knows that most people either don't know how to create a debug log or don't want to do it for fear of exposing personal information. If you aren't worried about that, and know how to create the debug log, you may want to do so. But my suspicion is that this isn't going to get fixed anytime soon, unless it actually bites a Kodi developer in the butt.
