PTC has been presenting and recording our weekly ROBOTalk Webcasts for a few years now. If you'd like to review the video archives, you can use the following links to get a list of all the webcasts presented by year.
I only found out about them two weeks ago (I wasn't in my team's google group until last week ><),
so it has really been helpful to go back through these.
To be honest, I am used to using solidworks and initially had some frustrations transitioning to CREO, but these talks (combined with How To Model Almost Anything) really helped me out and now I may even prefer CREO.
As a mentor, there is some really great material in these talks and they have helped pinpoint some side projects (i.e. elevator speech and team brochures) that I can suggest to students who don't seem to be working on anything else at the moment.
