I just purchased Adobe Acrobat Connect about a week ago and was asked about recording a webinar for later viewing. I noticed that in the documentation it says that it can be saved for offline viewing as an FLV file. I'm not a Moodle guru but that should make it easy to incorporate or at least allow you to convert from FLV to another format.
Here are details from Adobe's support site: http://help.adobe.com/en_US/AcrobatConnectPro/7.5/Using/WS9C2F5D55-EC79-4dae-8006-44E03914DC01.html#WS20F14479-39A1-42e2-AF0A-F8C2F1AA9BE4
I'm hoping to do this in about 2 weeks so I'll be learning the details.
