I have seen this if your Mac address used on different device meaning someone got your Mac address now. your server provider needs to lock your device to your device id, your isp, country...etc if they have that option available.
clear epg, while watching live tv press menu, settings, configurations, go down and click clear epg
clear cache, from home screen go to settings, apps, buzztv5, and click clear cache
from home screen click on live tv and it will open up buzztv app for you. now you have three option, Mac, XC api, and m3u.
if using your iptv provider with Mac address then use Mac option. your Mac should be displayed on top right corner and starts with 00:1A:79...... if using username and password then use XC api. if your provider gave you m3u link then use m3u option.
agree, the whole purpose of a streaming box is to download apps and stream but if streaming box has dedicated built in app designed for stream then your first choice should be onboard dedicated app.
rest Emporium explained it very well above this post.
whats your rooms temperature day time, night time and average?
do you have more electronics devices around X5 or X5 sitting on top of another electronics device?
whats your power mode set to?
do you have decent gap between device and surface?
mine stays slightly warm and no glitching issue.
sometime brand things give us problem too but really depends on user ends technical skills too. im not saying you dont have technical skills or lack of skills caused this issue but just saying
did you enter epg info when you added server?
I would say use xc api option instead of m3u. your username and password is in m3u link. so go to xc api option, enter your portal, enter your username and password and you are good to go.
do you have a pc keyboard to connect to it to see if that helps. if you do then turn off your box first, connect keyboard then turn on your box and see if that helps.
theres reset button on the side. hold it for 30 seconds. if that don't work then try turn off the box, hold the button and turn it on and keep holding until you see the recovery screen.
