Problems with the URL: How to record Adobe Acrobat Connect Professional presentation

In that post, I have already read, it is suggested to use a screen recorder: it is the last thing that I want to do.
Try imagine to stay an hour and half waiting the stream.

For this reason I tried to ask something else better.
Anyway thanks for your help.
