Hello I was watching other forums and I saw that in fabruary was some update of TRRPlugin.
This one what I have is very old
enigma2-plugin-extensions-trrplugin_v2.0-r064_py27_all
from may 2013
Maybe You can upload new one because in this I have always information that Server is down and try after 10 minutes.
My tuner it's VU+ Duo2 with VTi image.
Best regards
