Long story short:
IPTV works on Samsung TV, but would like to try it on different platform. I have no communication with the IPTV seller who set this up.
Is there any way to find the link/files from the TV or siptv if i have the tv mac address or is it impossible and I should just give up.
Search your emails? Look the through the settings of your program. Try remembering how you set it up in the first place.
Either you tried that or you lack basic troubleshooting skills
