I have I believe, the same camera and no disc. I just plugged it into my USB port and winxp recognized it and a moment later it was ready to use.
Then I started up Yahoo Messenger. Going through the menu picks there was one to use a webcam. Since I only have one webcam I guess Yahoo Messenger knew to pick it as the default. However, there is a menu pick I that allows you to select input I am pretty sure if you have more than one. Once I went thru the short (use it) button clicks, the camera was working.
I have yet to actually contact anyone to see if they can see me but I presume it will work as I can see me.
The point is, you do not actually need the disc to make it work. Just about any "webcam" capable program will let you send live video as long as windows recognizes your webcam and winxp does.
Good luck
