Currently it is available in experimental mode only -- by adding "engine:1" "dune_param" parameter ("URL|||dune_params|||engine:1") to the playback URL (if the stream playback is started by a PHP plugin, the use of this function requires to change the PHP plugin). This can be helpful when the native IPTV playback engine does not work good in some cases.
