This collection contains the original "The Chronicles of Spellborn - The Howling" gametrailer from http://the-howling.com, and an exact copy of the audio stream.
The .flv extension means Flash Video. You may play it with e.g.:
- mplayer: http://www.mplayerhq.hu
- VLC: http://www.videolan.org/vlc/
The audio was ripped with mplayer using the command "mplayer Within Temptation - The Howling.flv -dumpaudio", which dumps the audio stream of the movie to the original format and bitrate, in this case 128 kBit/s MP3.
