I dont know if its possible but could it be a fact that "enigma2-plugin-demoplugins-upnpmediaserverdemo" is not working due to missing tpmd support ?
EDIT: Error is "no module named ....", havnt had those problems with newnigma2. but unfortunally my USB tuner cant be added in NN2. The drivers install fine, but the tuner wont show up in the tuner menu.
