Do I need XviD to download a movie?

I want to download a movie from IsoHunt but I have a little problem. I still didn't download the movie because the name has XviD in it and i'm not sure if it needs that Xvid Codec thingy. You might think it's a stupid question but i seriously hate waiting 3 hrs for a movie that doesn't work without XviD.
"(name of the movie).2008.LiMiTED.DVDRip.XviD-XanaX" the movie's name looks like this...
So my question is : DO I NEED AN XVID CODEC TO DOWNLOAD THAT MOVIE?

sometimes but the best thing to do is go to a different movie website like solar movie or 1 channel

It should work on most video players, VLC media player is probably the best, it's the one I use
