For movies I’ve got a few scripts worked out, and have used them for things like the 1990-91 video catalog: http://www.sierra-collector.com/games/catalogs.cfm and the demos of some games like http://www.sierra-collector.com/games/about/67/index.cfm
I plan to do more in the next few months and would be interested in hosting the videos.
I use a program called Sorenson Squeeze to prep them for the web, and wrote a script to stream the files to my site (allows you to jump to any part of the video without waiting for it to download)
