Graphics and Animation file viewers

Hello All Someone sent me a file with .wmv extension. Nautilus shows that the file is a movie of some sort. Mplayer gives the following error message at the end: Playing Cluster150K.wmv Falling back on trying to parse playlist Cluster150K.wmv... ============ Sorry, this file format is not recognized/supported ================= The file has a funny name "Cluster" which might be some superset of an ordinary movie file. My question is this: Is there an authoritative site which discusses all possible Linux viewers for different file formats? TIA
