HELP! Starting procaster automatically begins camera playback

[umcom]

Planning on doing a webcast this afternoon, but whenever I start the procaster broadcast, it sends a "Play" signal via Firewire to the camera to play back the DV tape. I want to record both via Procaster, and record on DV, but the only way I can make this work is to remove the DV tape from the camera and only record via Procaster.

This does not happen when I use Wirecast, so I have to assume it's a Procaster issue.

Any ideas? The camera is a Sony DSR-570WS
