I downloaded most of the ******** **** Season 1 as avi files. While they work and they play fine in Real Player or Windows Media player they are kind of blocky and pixelated as some parts.... but then the other half the time they are perfectly clear. Could this be my graphics card and not the file? I'm hoping it is.

It's the more complex images that are blocky.... so I was just wondering if there would be a way to fix this.
