Sorry but I had already found these posts and updated the rytec.sources.xml file...I thought you where talking anout updating something else
So the problem still persists, when I launch EPGimport it says it needs to download the data, and when I tell him to do so the plugin closes itself immediatly.
I wonder if it's maybe a compatility issue due to the fact that OpenPLi 6.0++ is based on the kernel 3.2 (while OpenPLi 4.0 was based on 2.6 or 2.7).
