How can I get window media player to play avi files?
You will need to get codecs or use VLC which does not require codecs. I recommend using VLC media player (it can play anything). Best part is it’s free, open source and completely free of spyware. It is also the most popular player out there. VLC media player is a highly portable multimedia player for various audio and video formats (MPEG-1, MPEG-2, MPEG-4, DivX, mp3, ogg, …) as well as DVDs, VCDs, and various streaming protocols. If you also want free codecs, the Divx codec or K-Lite codec pack should allow your media player (e.g. Windows Media Player) to able to play 99% of all the videos that you download from the internet.
