I tried a lot of Windows Apps. All those Windows Store Apps like MyIPTV player really suck. Bad UI and advertisements.
VLC has a bad channels management. Perfect Player has an catastrophic UI.
Seriously, use the SFVipPlayer
You can download it here: ************************** and use the v1.2.4.8.
(The 1.2.4.9 version is in fact the 1.2.2.9. Probably the developer made a mistake.)
On top right, click on + and add your MAC, Xstream credentials, or the playlist URL.
EPG works, Subtitles work, Channel switch is fast. No ads. IT JUST WORKS.
Thank me later.
