Use OpenPLi 5.0+ IPTV, as the OpenPLi 6.0+ IPTV is built from the original OpenPLi 6.0 sources and is not working well in IPTV, better than their old OpenPLi 4.0 with GStreamer 0.10, but not good yet. The OpenPLi 5.0+ is built from the original sources (GStreamer 1.8.3) but was adapted with the OpenPli 4.0+ IPTV recipes to comply better with IPTV, so if you want good IPTV take first OpenPLi 4.0+ IPTV, or OpenPLi 5.0+ IPTV, but forget about OpenPLi 6.0/6.0+ IPTV if you want stability of IPTV.
