      brad=>Well, there is a way. don't know if its what you're looking for, its
      brad=>called "Streaming Video". Though, that's not a foolproof solution either
      brad=>as there are a number of streaming video capture tools.
      brad=>Ever heard of Real Networks? If this is a business thing, look there,
      brad=>and probly Akamai. Google a bit for "Streaming Video Servers" or
      brad=>something along those lines. Undoubtedly this will lock a user into
      brad=>using a proprietary video format with little alternate OS support and
      brad=>lesser quality than regular formats.

      To clarify and correct a few points:

      RealNetworks supports the following OS's
      Compaq True 64 5.1 & 5.1a
      FreeBSD 4.0 & 4.5
      HPUX 11 & 11i
      IBM AIX 4.3 & 5L
      Linux Kernel 2.4.18
      Sun Solaris 2.7 & 2.8
      Windows NT & 2000

      As for locking the user into a proprietary format, the Helix Universal Server will stream:

      (Taken directly from the web site)
      RealNetworks: RealAudio (.rm), RealVideo (.rm, .rmvb), RealPix (.rp), RealText (.rt)
      Macromedia: Flash (.swf)
      Microsoft: Windows Media (.asf, .wma, .wmv)
      Apple: QuickTime (.mov)
      Standards-Based: MPEG-1, MPEG-2, MPEG-4, MP3
      Image Formats: GIF (.gif), JPEG (.jpg, jpeg), PNG (.png)
      Other: AU (.au), AIFF (.aif, .ief), WAV .wav)


      brad=>This is kind of a low hanging fruit problem as well. If you have a
      brad=>video, just disabling right click over the link maybe enough to deter
      brad=>the most number of straight downloads. People wise enough to look for
      brad=>the video in Cache directories are also wise enough to search around for
      brad=>DRM circumvention tools anyways. If not search, create (very very very
      brad=>very very very very small minority, but it only takes one).
      brad=>Whatever the solution, its outside the scope of "normal" CGI problem.
      brad=>Given that certain web browsers (*cough*MS IE*cough*) will ignore
      brad=>caching directives of the HTTP Environment ("HTTP-Equiv: no-cache" or
      brad=>something like that) AND the EXPLICIT preferences of the particular
      brad=>user, it'd be all but impossible to prevent the movie from showing up in
      brad=>the cache of the browser.
