00032 // Description : A MovieVideo is actually any source that provides
00033 //               a sequence of video frames.  That could include an
00034 //               AVI file, a digital camera, or an internet TV station.
00035 //
00036 //               The difference between a MovieVideo and a
00037 //               MovieVideoCursor is like the difference between a
00038 //               filename and a file handle.  The MovieVideo just
00039 //               indicates a particular movie.  The MovieVideoCursor
00040 //               is what allows access.
