The good news is the fair use doctrine under U.S. law. Judging from the analysis presented in the Wikipedia article, speedrun videos may be considered fair use because:
* They are transformational rather than merely derivative
* They don't affect the potential market of the games (except arguably positively)
* They advance the knowledge or the progress of the arts through the addition of something new
Issues include whether the videos show a substantial part of the original work (this likely depends on the nature of the game), and possibly also whether the videos are used for commercial purposes.
It'd be interesting to know what the Internet Archive's rationale is for hosting speed videos; does anyone know?
