FLV is the video format for most video web sites (youtube, video google, etc).

Unfortunately, Windows Media Player doesn't support FLV files.

Fortunately, we go to the trouble to provide a downloadable version of our custom FLV player for Full Access subscribers. On the right toolbar (any page except the forum) you will see a "subscriber downloads" button. Click that to get our downloadable FLV player. Right now it is the old player, but shortly you will be able to go there to get the new one.
