IPTV: "m3u8 list file not found"

[greencajun]

Hi,

I downloaded the official Ariva IPTV sample file (iptv.txt) file from
http://www.ferguson-digital.eu/en/faq/odbiorniki-ariva-50-250/439-what-is-my-iptv.html

When I try to install this file, My IPTV > Add Channel > USB, it says
"m3u8 list file not found"

What am I doing wrong?

Thank you,
gc
