Greetings Geeks, I have an online product called wwww.thebestumpire.com. Basically, it's filming for baseball umpires so they can practice without having the game on the line. Here's what I'm trying to do. I will have about 10-20 registered participants at one time for about an hour. I'm trying to set this up where the head umpire will be able to: 1) start,pause, and stop the filming so he can describe what's going on during the pitches. all the while the participants will be able to: 2) view the video from their computer. 3) be able to hear what the head umpire is explaining. So it's like a conference call with video that the instructor has the ability to start,stop, or pause. Any suggestions would be appreciated, Thanks Geek Nation! Matt.
