Iptv on openbox v8

[Anth1]

Hi hope this is ok
Trying to load the m3u file.
I’ve sent it to my usb then stuck it in v8 under webtv then press yellow and I get failed everytime. Tried changing file name but not sure if I’ve got the correct capitals and dots in the correct place.
File works fine on laptop via vlc.
Any ideas?

You press the blue button to upload your file the yellow dumps the old files from the receiver
