This is the best I can offer at present time.
https://www.youtube.com/user/intergraphcorp/search?query=dynamicOnce upon a time, some but not all of these videos were able to be downloaded completely and directly in wmv format. Even then, you'd have to provide personal information and receive a unique link via e-mail, but at least you could keep the webinars.
Shortly thereafter, they moved to making it streaming only. Sigh.
Shortly thereafter, they were further fragmented by being streamed from different collections. Double sigh.
Now they seem to be unavailable in their entirety. Hrm.
Well, Dave, Richard. I have 2 of these particular WMVs... modal and harmonic.
Do you have the other 2?
May I share the 2 that I have?
