FLV Player is compatible with Windows 2000, XP and Vista, supports both local and internet streaming content, has full screen mode and, best of all, its free. For more information refer to the annotated screenshot below and consider reading the FAQ and changelog.
An important note to keep in mind: FLV Player uses the Macromedia Flash 8 FLV Playback component to play .flv files with. This component functions best when your .flv contains valid metadata. All .flv files created with recent encoders such as Macromedia Flash 8 Video Encoder have their metadata injected automatically. However, if you wish to view older .flv files they may not contain up-to-date metadata. I highly recommend you use Buraks FLV Metadata Injector to automatically inject correct metadata into those files.
