play around with your cache size with adbfire and try the other tweaks in this addon https:/ /github.com/elmerohueso/xbmc.repo.elmerohueso/tree/master/download/plugin.program.FTVtweaks
but it sounds like your just seeing server related freezing... the server is sitll in testing and has been acting poorly for me lately too.. better so in the last day or so though.
Hey psycon my mag 254 emulator seems to not like nfps as I've been watching TV via stalker on kodi no issues since I first posted so I switched to the mag to see and instantly freezing thx for your input btw
Interesting enough I get no freezing with the mac I made up on the emu on my phone so I used that and changed it to mag 275 and no freezing fast channel response
