Hello,
my idea: I create a XML-File with Quizname, Answers, (Tick the Right Answer), Timeline Number and then this Quiz appears in the JW Player. All results (right/wrong) would be saved, and at the End the user will get the results "you have 2 from 10 correct answers".
with this same methode you could do something like "did you like the movie" at the end of the video... ;)
anybody there who could realize something like that? i think other people would love something like this to!

There's currently no plugin that does this, but feel free to implement it!
