Hmmm, that's weird because, when I dev it, I choosed to always display timeshift remaining, not only when paused.
By this way, it was possible to always see counter in the OSD (by clicking on info, even when TV is played).
And each time, counter continued to be updated.
But, maybe is it a specific thing with video fullscreen when paused ? (Global MP thread frozen ?), don't know.
Can you please point to me what is the skin file for this then, I will gain time and, try a test.
