Note that .rm can also be uploaded, but the quality will be inferior to the format noted at left.
For TechTV, we take the original (can't be .flv - must be a standard format YouTube accepts) and upload with same info as on the TechTV page for that video

Internet Archive

any of those mentioned here

-

Internet Archive does not place restrictions around uploaded content, but as it is a true archive, files cannot  be managed easily once uploaded.
OCW posts iPod-quality MP4s on Internet Archive (http://www.archive.org) to support users who cannot view embedded YouTube videos (generally high schools have blocked access entirely), are unwilling to download the (free) iTunes application, or use Linux.
There is no general MIT OpenCourseWare collection in this space. Instead, files are collected by course (identified by term and year: 8.01F99), and basic metadata is assigned at both the file and collection level: publisher (always MIT OpenCourseWare), contributor (the course instructor), title (for collection and file), date (of the recording), sequence (track 1 of 37), description (at the collection level), and keywords (at the collection level.
