Hi, I took delivery of my G series box today. Just need a bit of advice about using the"buzztv 6 app" , including the remote. Is there a way to access the epg guide for a group , whilst watching a channel , without having to press down. press main menu, scroll down to "epg" and then select it. There isn't a dedicated button on the remote to access tv guide ? Also the 4 coloured buttons on the remote , red gives a channel lock option , green subtitles option , yellow and blue dont appear to do anything . Can one of these be programmed to open tv guide ?
