VIDEO PLAYER NEEDS CODECS

The Annoyance:

When I try to play a video, the video player cries out for some codec.

The Fix:

Multimedia files always employ some kind of compression to make them smaller. Smaller files download faster across the Internet and take up less space on hard drives. Some compression is mild, with very little (if any) loss of the original data, while other compression is very aggressive, with notable loss of the original data. A codec (short for compressor/decompressor) provides the instructions needed for an application (e.g., Windows Media Player or a video-capture program) to compress or decompress the data for a particular file format. Popular codecs include MPEG, Indeo, and Cinepak.
