Hi. Had delivered today the octagon sf138, all set up & I personally think the picture quality is better than the zgemma. I'm looking now for some tips, tricks & advice to get the most out of this receiver. I would like a nice VM skin also on how to pull the screen resolution in a little. Hope I've made the right choice on moving my zgemma on & going for the octagon. Currently running openATV 6 on this as its what I'm used to. Any help or advice will be appreciated
