As Plex API is missing some features and plug-in uses urllib2 to handle some things in m3u and xml files, it might be limited in ipv6 department, however playlist and logos are fetched by Plex and there is nothing I can do about that.
Anyway, could I get a sample playlist or logo, or better both?
Strange behavior.
Streams could be played from ipv4 or v6 server. But playlist url or logo-tv url should be ipv4 only. If ipv6, data aren't retrieved (no requests).
