I found a problem with the URL stored in E2m3u2b_iptv_iptv.sources.xml which contains an "&". This I also wrote an other forum where I downloaded the plug-in originally.
This is what I noticed:
I want to also read the EPG and that did not work for me. I tried it with stand-alone EPGimporter and that did also not read any events in.
I looked in the E2m3u2b_iptv_iptv.sources.xml file and noticed that in the URL's the "&" was replaced with "&". After removing "amp;" the import with the standalone works again. I can't test it with the E2m3u2Bouquet plugin because during the processing the E2m3u2b_iptv_iptv.sources.xml is overwritten.
