Tvheadend

If I pause channel, then switch to different one, the new channel is still on pause.
If timeshift is continuos, then new folder is created an buffer files are written for new channel, and I can un-pause it;
If timeshift is on-demand, new folder is not created and no buffer is written for new channel (but new channel is on pause and I can resume it) - this is weird.

I expect that either after channel change, new channel is not paused but live; or, for on-demand mode, timeshift buffering starts for new channel immediately if it's on pause.

Not sure though, is it a tvheadend/pvr.hts/xbmc issue?
