Most camcorders come with a USB cord for transferring the video to a computer. If you're using windows, it should prompt you after you plug your camcorder in to select what type of device it is. You'd select camcorder and you're off the races.
Windows comes with "Movie Maker", not the best video editing software but better than nothing. You should be able to transfer the video using that software ... its pretty straight forward. Once its been transferred to your hard drive, you can log into SBR.tv and upload it to your account.
