mbone and realvideo

[brett watson <bwatson () genuity net>]

  we're furiously working to get mbone stuff... in the mean time,
we'll still tape and dump to realvideo.  several folks have complained
that the player only runs on windows, not true:

freebsd (both dynamic and static link)
mac os
os/2
win95/nt
solaris (2.4 and 2.5 sparc)
sunos 4.1.x
irix 5.3/6.2/6.3

ps.  i'm still open for other formats to dump to.  real-stuff seems
most accessible to everyone.
