I get no loading bar and black screen on 422. Anyone else?

I am pretty much done with IPTV after 2 weeks. (Mag254, 100mbps FIBER internet, rockettv) Video quality is poor on all of the main channels Audio quality is also poor on those same channels Freezing channels occurs on every channel I have tried at some point, which pretty much ruins the tv...

I have to say that the guide and channel list is awesome. Wide variety of channels. I need to figure out a way to remove most of the international channels because I will never watch them. It seems that most channels are SD or below in video quality. Is there plans to add HD channels? Also...

Looking to get back into it. dont know where to start with IPTV or IKS. I hope someone can just give me a suggestion on where to head for the best video quality, with the least downtime, and most channels. I would like to record as well. Kodi? something else? Thanks all!
