My Old Video Cassette Collection

This is my old video cassette collection mostly documentaries I would like to share with anyone who has similar interests. Sorry for the poor video and audio quality but my video tapes are very old and I only recently got a PC strong enough to run the video converter software. If anyone knows how to clean up audio and video and what software to use? Please drop me a line with any links. Hope the poor quality does not spoil the documentaries too much. Regards
