we use the control computer as a record machine, the windows media encoder captures the screen and audio coming from the XAP (both local and remote), this way we capture the PPT + audio, if VIC is running u can even select the videostream with the lecturer and overlap it over the PPT. This way we have a wmv of our seminars, etc.
What i was trying to do now is to record the actual AG session using RTPdump, with this program i can record video+audio+PPT (as screenstreamer uses RTP), i still have two problems: 1.- The size of files as all the videostreams are recorded: I'm trying to solve it using RCBridge 2.- The filesize limit of the files generated by RTPdump (2GB): I've found some fixes done to RTPdump.c to eliminate that software limit (havent tested it yet). Using this second method I can later use windows media encoder to obtain the wmv record of the session. Lately i've found a program called MboneVCR, though I havent tested it yet.
