If you download Youtube Video Downloader, it has the option to change the format. Then, you can change mp4 to wmv, and watch it with windows media player.
Media Player Classic or VLC
or you could download the app tube mate and download them from their
Adobe Media Player? My Videos work with it.Else you can use a converter and use the required player.
Use VLC (VideoLAN) player. Find it on Google.
