What is that for? for videos? If its for videos you can download the rock player and it will play most video formats. What is this for? home security? if so, just use ustream and ustreamviewer, totally free and you can see whats going on in your house. Theres even apps to remotely control your home computer.
the ustream app is nice, you cant control the cameras tho heres how it works. Get a free account at ustream.com (its kinda like youtube) Using your computer create a channel.(downside is that I think everyone can see it) The start broadcasting, using the ustream viewer look for the channel and walla. I had 3 seperate computers running 3 channels. I was able to get one laptop to run 2 channels at a time with two web cams connected but you will need one with a fast processor. I hope this helps.
