BerniceC: Hopefully someone will jump on here to help better then me - I'm thinking for some movies, you need special codec's loaded to properly view movies. I had to load a lot a long time ago, and since then I have no problem playing just about any more - but I'm pretty sure it's because I loaded all the codec's that I needed.

Now I'm not 100% sure about this - but you may want to get this: http://www.free-codecs.com/download/K_Lite_Codec_Pack.htm

It's a pack with all of the most popular codec's on it - and says it will allow 99% of movies to play correctly. Again, not 100% sure about this so please don't get mad at me if this blows up your computer or something.

BIG BAD WOLF:  I just tried a download using uTorrent 1.6 and the file played fine.  It too is an avi.  It might help to know what kind of computer etc Bernice has.  I'm using Windows Media player 11.  ;)

Gr☺uch☺: It depends on the AVI and how it was coded. Different programs use different "codecs" to encode the move in .avi format (or other formats). Some will play on Windows by default, while others will not.

Wiki page on Codec's: http://en.wikipedia.org/wiki/Codec

Basicly - some codecs will make files smaller, while others may keep the audio beter, while others will keep the video better. This is at least how I understand it - at least without getting very technical and such.

BIG BAD WOLF:  If a person had the latest version of Windows Media Player could they still need a codec to play a particular file?  I know that in the past I've had this problem and had to download form the site to update the Player.  

Gr☺uch☺: I'm not sure (I don't use the latest version of Windows Media Player) - but my guess is that it is impossible for WMP to have every codec out there - so I would guess that even with the latest, you may sooner or later run into something that needs a codec.

... and I'm far from an expert - I could be wrong in all of this - if so, I'm sure someone will correct me.

BIG BAD WOLF:  I'm not sure about it either.  :)  I'm sure someone will know the answer.
