For a piece of freeware in a category that's rife with scams and junk, FLVPlayer4Free stands out as a solid, reasonable program that does what it says, offers a bunch of options in the deal, and does it all without any annoying predatory advertising.
The program starts off with eight skins, most of which provide significantly different looks beyond just a new coat of paint. The options menu, which is only right-click accessible, provides hot-key and menu access to several useful choices. These include fixed resizing to double the original size or full-screen viewing, maintaining the aspect ration, smoothing, nearly 20 languages, and rollover hints. It also has a built-in screencapper.
The app is not without its flaws, though. When installing, users must opt out of downloading a video-format converter made by the same publisher and the URL downloader doesn't work with YouTube. Still, the player is light on resources and generally performs as promised.
