Tvheadend

This isn't bug you must use pvr.tvh instead default tvheadend plugin.

So, you're saying the bug is not in tvh itself, but in the respective xbmx pvr addon, right?

With respect to timeshifting, tvh.hts (the pvr addon bundled with xbmc 13.2, openelec 4.2) is buggy, but pvr.tvh (avail. from https://github.com/adamsutton/xbmc-pvr-addons) works fine? Will test this tonight.

BTW: Is pvr.hts end of life? Is pvr.tvh supposed to replace pvr.hts?

Well, does not work. I used the combination of openelec 4.2 (containing xbmc13.2), self-built pvr.tvh (master), self-built tvheadend (master, 3.9.1600).

I guess, timeshifting will only work with a recent openelec master / kodi build.

I compiled tvheadend, XBMC and the reprogrammed pvr addon (tvh), everything from scratch:

And I also was facing the time shifting flaw described above. In the XBMC forum, they answered this is still a known issue (bug in the pvr addon, XBMC or even tvheadend? no one knows).

It seems that it's fixed now: https://github.com/tvheadend/tvheadend/pull/516 . Please, confirm.

Confirmed. Works like a charm now. Thank you for the fix, perexg.
