@ all: Thanks!

Regarding video capture, I use Fraps. The downside with the program is you need a wicked fast PC to help minimize lag and enough hard drive space to store the RAW video files. I can end up with multiple 4GB files of video data which needs to be rendered and compressed in a video editing program and PC performance comes in handy here as well.
Anyway, I use FRAPs and have even encountered lag, but you have to calculate the amount of memory the video takes, versus quality, video format/transfer/uploading speed, when it comes to 3D games, this can take up more. However, Fraps seems to be the best at capture SC4, its not 100 percent free though. CamStudio on the other hand records games like SC4 for free, less memory space then Fraps, but I have not gotten it to record sound for any game. I just had to make it seem that way by editing existing noise.
I have Fraps, but only the free version as I won't get the full version. As for CamStudio, it lags a lot for me. I alter the capture rates a lot but without luck.
Thanks for your comments and advice

netmod: Here's how I inserted my video:
I took the video URL (
)
I then edited the video URL to get rid of the watch, the ? and the = surrounding the 'v' (so it's like
http://www.youtube.com/v/ZDE7osq0ehw)
Then, simply click on the Flash button at the left of the row above the smileys, and paste the edited URL there. Also, editing your resolution (where it says [flash=(resolution)]) is very useful.
Hope that made sense,
Sam =)
