RT International236 and RT UK, RT US are all running at this time, channels have done some moving so there is a need to keep up to date to get what you want.
I only checked 921 and 867 as they were in the. Middle of your list, we're working when I posted a new stilll going now.
Do expect you know of a lot of Down channels and expect many will come to life ((hope. So))
My Fuse worked well on the channels this morning but was very slow changing channels, after changing to the kodi section for a couple of hours it would not connect again, have tried a few resets without any change so will wait it out.
Try a Google DNS in router and Box and do you have DL. Speed your first box may haver good true would also say the Avov products such as the fuse run very well.insides.
If a beta version is available and you use it you are taking a chance on how well it will run, think it best to load tested versions. To avoid future problems.
I have not seen a single buffer the last three days whilst watching my Sonin Laws mag254 and he tells me it is always that good on English speaking channels.
