BSplayer is windows player for playing back avi/asf/mpeg video files. It can also display subtitles. Also available are different skins for this player. Please note that this is a general multimedia player for playing back AVI files.
Different AVI files may be encoded with different "codecs" (compressors and decompressors ; COders and DECoders), so by having an AVI player does mean you can play every single AVI file in the world (you`ll need to separately download and install the codec for the AVI file as well).
