Greetings here to show you what error occurs to me on YouTube when searching and releasing for playback.
So I put a urlparser to set it up for me
Youtube is working, not 100% but working, try this fix, in each folder remember to delete the matching .pyo files, so delete "hostyoutube.pyo" in the hosts folder, "urlparser.pyo and youtubparser.pyo" in the libs folder and "youtube.pyo" in the extractor folder, make sure you put the files in the correct folders then reboot the box
