You should be able to export it to a quicktime movie file. .mov file straight from Final Cut or I movie whichever you have. Save it to your desktop on the Mac. Then you can insert flash drive and transfer it to that, then you can transfer the file from that flash drive to your PC. Your PC should have a quicktime movie player, and you shouldn't have a problem uploading it as a quicktime movie file to Vimeo or Youtube, etc.
