If there is a specific lecture you need to see, send an email to webmaster@biotech.wisc.edu with the date, time and title of the lecture you are trying to view. We will prioritize lectures that are requested, but the best strategy if you need to see a lecture NOW is to find a Mac or a Windows 7 machine that can play the current version.
