Playlist loader and pastebin issue.

Just managed to get to grips on how to create a playlist loader from a pastebin file however one thing bothers me and has left me scratching my head.

I can watch a stream from a browser without a problem however when I put this in a pastebin file it does work.

Example below

#EXTM3U

#EXTINF:-1,ONE TV

Hope that this is clear and appreciate any help.
