Script installations from http://iptvplayer.vline.pl are giving me Service Temporary unavailable.
Solution for OpenPli8 that worked for me
1 - Use a nightly built version until 8.1 is released
2- Download IPTVPlayer from github (I used maxibambi fork)
3 - FTP files to '/usr/lib/enigma2/python/Plugins/Extensions/IPTVPlayer'
4- opkg install libcrypto-compat
5- opkg install enigma2-plugin-extensions-e2iplayer-deps
5- cd /tmp && rm -f ffinstall.py && wget http://e2iplayer.pkteam.pl/ffinstall.py && python ffinstall.py (the one on iptvplayer/vline.pl not working at time of posting)
6- reboot and config IPTVPlayer
