Thank you anyway for all the help and guidance, much appreciated!:)
I tried copying the url into the "open network stream" in vlc, and then I got this message again "insecure something" and I had two options again, either to "check verification" or something and "abort". And then only the audio of the video starting playing again, like had happened before. But then something new happened. The whole pc kinda froze, it didn't completely freeze. I could move the mouse, and I could enter ctrl+alt+F1, but when I got there it was just ouputting lines and lines and lines of text and I couldn't do any commands. So I forced my pc to shut down, and when I turned it back on I couldn't use Midori browser again. So I guess it's time to wipe hard disk and reinstall again :P a man's gotta do what a man's gotta do, right? :P
