how do i turn an .flv video file to a media that windows media will play?

Answer 1

You might consider downloading the KLite Mega Codec Pack as it will give you the capability of playing .flv files natively. It also plays FLAC, OGG and most any other format you can name!

Beyond that, one converter for FLV files is found here:
