That's a lot of questions, I only had 1... LOL
While this is a bit of thread derailment, I can answer some of them. For the others, hop over to the TvH thread and ask in there.
The best Docker/thread is located here http://lime-technology.com/forum/index.php?topic=37671.0 Install (preferably) from Community Applications.
Does it support schedules direct? - Yes, easily - no. Meaning, it does support it natively, but setting it up is a bit of a cludge. For that specifically, look here (quoting myself here). http://lime-technology.com/forum/index.php?topic=37671.msg442261#msg442261 more info above that post.
Remove commercials, yes, but have not used it as of yet.
Expire recordings, I'm pretty certain yes, however wasn't spelled out exactly as "keep 10 recordings of XXX recording" however the specifics would be better asked in that thread, or better yet on the TvH forum or even the TvH subforum in Kodi.
Thanks....yes, I can ask for sure....just trying to hit the main points if there was some reference feature comparison already done. Those are the main things I can't live without as I depend on them....but the little reading I did do on TVH seems to want to include those "clugy" ways which I am not a fan of as they usually are the first to break in upgrades. Oh well, always tradeoffs. I appreciate your feedback and may give it a go since that is one thing that Docker makes easy (i.e. not messing up your host system).
