I got a Mi Stick for Xmas and i added IPTV to it, however sometimes it buffers and stutters quite a lot on my TV, however on my phone with the same provider and app ( IPTV pro ) it works without issues.
Also on my PC i configured the IPTV service to work on VLC Player and it works without issues as well.

It it the Mi Stick's fault? I don't quite get why it works well sometimes and some other times not.
How much ram should is advisable for an Android Box with IPTV to run smoothly?

Thanks in advance.
