These instructions are for Windows (skip the next paragraph and go to Windows instructions).
ANDROID TV BOX / SMART TV APP USERS:
Use the same instructions as Windows (below), but find ProgTV on the app store not via their website.
If you use a remote control and do not have touch screen (smart TV / Android TV box) you will need to do the following:
Using a web browser (on computer, or phone) copy the M3U URL from the "My Account" page,
go to https://tinyurl.com/app and paste the long URL in there, type a random sequence of characters as the "alias" then click "Make Alias".
Then type the new tiny URL in to ProgTV.
WINDOWS PC INSTRUCTIONS (ignore the previous paragraph for android etc).
Install ProgTV from this page. Look for "ProgTV Professional for Windows x64*". Download that file, once downloaded open the file, this will install the software to your computer.
Find ProgTV on your start menu or desktop, open the newly installed program.
Select "IPTV Client"
In your web browser visit the "My Account" page on our website and copy the "M3U URL" (click the button to copy the text!)
Back in ProgTV, paste the M3U URL (you just copied this) in the "Play list" box.
In the "Guide" box enter: https://britishtv.club/guide.xml (type it or copy & paste it from the "My Account" page).
