Just make sure that when you open the scripts document they send you, it's opened in notepad++ or wordpad.
Notepad can mess it up
If you get stuck drop me a pm and I will try to talk you through it.
Its really as easy as this:
Open putty in telnet session, and log into your box as root.
Open document sent (either of the ones mentioned above) and copy the full script.
Right click the blinking cursor in putty.
The script will run and install (if all ok and done correctly)
When its all ran its course in putty you should see the root command and blinking cursor waiting for a command. ( It may reboot if script has reboot as final input)
If it does not reboot automatically then type reboot in the command line and hit enter.
If all has worked ok, then in your favourites section of the channel list, you should see NEW iptv sections. Select a channel and try it
