RE: good quality webcam for linux?

Are there actually linux drivers for the Dazzle Hollywood DV bridge?

I think I might have been a little unclear before, I don't need to
actually capture the video, I just need the video stream being sent to
video0 so that another program, like xawtv for example, can access it...
