The link above is to the Audiodharma Free online Mindfulness (Vipassana) meditation course.
The lectures are by Gil Fronsdal. I've been listening to talks by him on the Audiodharma and Zencast podcasts for the last year and a half. (easy going, insightful, fun) Find mindfulness fits well with my Ashtanga practice. Gives you great tools to help you stay present.
Still possible I think to "Audit" the course which, for the non Americans, means follow the course but without the feedback from tutors. But if you miss it or this is a bad time to follow the whole course you can find intro to mindfulness meditation lectures by Gil on the Zencast podcast on itunes.
Here's the course outline
