The free FLV-Media-Player is a standalone Flash-Video-Player which allows you to watch any downloaded FLV-Video-Media-Content. This utility can come in handy when viewing many FLV and / or H.264 files, as it doesn't require a pre-installed Adobe Flash OCX Plugin. The player has an easy and intuitive interface with many options.
