To extract the movie, you have to point FF8FMV to the data file on one of the FF8 CDs (not the install CD). It'll present you with a list of movies... pick one, extract it (make sure to pick someplace besides the CD to extract it to) and then drag it onto Binkplay.exe to watch it. If you have downloaded the Bink Player and installed it, you can just double-click the movie to watch it.
