iptvarchive NOT used standard infobar/player of enigma but own where is not defined skin part (missing in the code of plugin) but skin part of plugin player:
CODE:
class iptvArchiveInfoBar

is readed from active skin as:
CODE:
self.skinName = "InfoBar"


FDHG17 in mode "Extra screen only" disable definition of screen "InfoBar" and this reason why nothing is displayed while playing stream

result: this not a error of FHDG17 but missunderstanding between plaugin iptvarchive and active skin without "infobar" screen definition

possible solutions:
1. adding to the plugin code iptvarchive skin part
2. change reading skin part from active skin to more possible screens as is usually with priority
CODE:
self.skinName = ['iptvArchiveInfoBar', 'InfoBar']

I recommended to the author of the plugin to use 2. solution - skinner can define own definition and if is missing in active skin the plugin use "Infobar" definition

BTW: in the next update of the FHDG17 I will add definition of the screen 'iptvArchiveInfoBar'
