[QUOTE="shidhet, post: 1681033, member: 138755"] DivX files are simply a compressed form of AVI files. You'll notice the file extension for DivX or XviD files is still .avi. DivX is a very good way to greatly reduce the file size of video files with much less loss of quality compared to older methods like video CD (MPEG1). But, compressing an uncompressed AVI file will of course result in lesser quality than the original uncompressed AVI. DivX is a very high quality way to compress video files. But, the original files will always look better. 4GB+ DVDs are often compressed and converted to 700MB DivX files when people post them on the web. The DivX files look pretty good considering the great reduction in file size. But, they don't look near as good as the DVD. Think of DivX for video as you would think of mp3 for audio. It's amazing the quality that can be retained while greatly reducing the size of a file, but an mp3 will never sound as good as a CD it was compressed from. It's possible the AVI files you downloaded were already converted to DivX or XviD and your friend just compressed them even more. It's not common to download uncompressed AVI files. You can use a program like AVIcodec to analyze just about any video file and get all the information about the file.
