Explain the use a little more. Do you want to use it as a webcam for videoconferencing or for sending video-emails to grandmother?
If the latter, you can capture in DV and convert to MPEG-1 at a low resolution and bitrate and email to whomever. Don't know if you can use it for live web conferencing though; I haven't heard of an application that can do all that on the fly from DV.
