Similar boat to you op, my iptv supplier suggested switching to stock openatv, ipab support page suggested making sure they weren't set to hide.. the only way I could get them to display after epgrefresh was to hit red, 4, 4 to delete the iptv bouquets then they reappeared in my bouquettes as if by magic although not updated (my iptv supplier has vod) the epg was accurate though.
At the end of my tether with it lol. Lemme know if you get it sorted.
