The "Other" usually includes your OS, typically is takes about ~11GBs, plus documents, etc...

I had this same exact problem and found out that final cut pro was duplicating video files. First you need to use OmniDiskSweeper to find what files are taking up space and then you can delete them. I deleted my duplicated movies and it worked like a charm. You can get OmniDiskSweeper at http://www.omnigroup.com/more . You need to make sure to only delete FCPX Render files. These are the backup files for Final cut pro. The OmniDiskSweeper program will show you what's taking up space but make sure not to delete files you need or it can cause problems. I would do a search if there files you don't recognize. If there FCPX Render files you should be fine
