Hello and welcome to Justanswer!
I'm a expert on the german site from Justanswer and I have seen, that your question is still unanswered.
I don't know if I can help you, because I'm only a expert for electronic and computer questions and not a teacher for the german language, but I'm a native speaker from bavaria. So I would try to help you. Do you have a link to the youtube-Clip for me?
