You never mentioned your operating system, but since Taksi looks like it's Windows only, I'm going to presume you're using Windows. In which case, CamStudio works well, although I've found it somewhat sluggish. BBFlashback Express looks like it may be a better alternative, although I've never tried it (I'm currently using Debut video capture, which works very well, but isn't free; there's a free version available, but it likely has limitations on it).
