Well, I've tried Adobe Premier without any luck. It still only seems to allow you to view one input video at a time. I can add more than one, but I can only view one at a time rather than both of them side by side or above one another. Maybe I just can't find where to set that up, but I've been through the help file and can't see anything about it. It does allow 2 video displays, but they seem to be one for input, one for output, and they cannot play at the same time. I did look into the multicamera thing, but I can't seem to make it do what I want. That may be how it works, but I can't figure it out and the help file doesn't really explain well.

I'll try Sony's and see if that has what I need. If you know how to make Adobe's work the way that I need it to, please let me know.

EDIT: Ok, I figured out how to do it finally with Adobe and also tried Sony. Thanks for the help. Unfortunately, neither is as easy to work with as I'd like, but they at least do the job.
