It sounds like an API version issue - you're installing the wrong version of the right addon (that's pvr.hts), and it's not compatible with core Kodi. I'm guessing beyond that - maybe do some legwork on that version number, perhaps you're installing from the wrong repo, perhaps someone has forgotten to update a version number, perhaps you've got some old code that's refusing to get overwritten.
There's a thread on the Kodi forums here about pvr.tvh, which will ultimately replace the version you're trying - there may be something in here - or perhaps even try this addon instead:

Otherwise, this is an XBMC issue rather than tvh, so you're more likely to get some joy on that forum anyway.
