Downloading a streaming video off the internet?

I've tried searching for ways to do this off of Korean video sites such as daum, mncast, etc., but most of the helpful sites are specifically for the more popular sites like Youtube and such. A lot of the downloading programs don't work for me, and I'm wondering if anyone here specifically knows how to do it from those Korean sites.

I'm asking because I mainly want to bring some videos of kMS content to global maplers. Thanks!

I believe FF allows you to take whatever you want from any site and put it on your computer, this including video streams of course. Not sure if it's part of the program or an add-on. That's only one of many ways though.

The Firefox add-on is called Download Helper, I believe.

Firefox Addon:

Down Them All!

Is probably going to be the best tool.

Thanks, I finally got it to work! I've started uploading a complete pink bean battle; the whole thing should be finished in a couple of days =]

For some reason, it doesn't work with mgoon though, but it does work with all the other sites.
