Is it possible to capture video via the stream, not just a screen grab?

My problem with the video -- I am trying to capture a webinar. Unbeknownst to me, a Vista message was popping up throughout the presentation and that was all captured.

Is there anyway to avoid this? I was hoping this would be like the Media Capture, where is simply detects the stream and captures it, regardless of other windows or popups.

Thanks.

Webinars are different. Some of them can be downloaded with Replay Media Catcher, others can't.

To avoid recording Windows Vista messages popping up throughout the presentation when you use Replay Video Capture:

1. Hit the Settings button
2. Check "Keep Replay Video on top" in the Miscellaneous group.
3. Hit the OK button.
