We live in a time when virtually anything can be found on the Internet. This can be both a blessing and a burden. Those interested in downloadable video confront a wide variety of file formats that may not be compatible with a single viewer application on the PC. As these different formats proliferate, so do the applications to view them.
Lamentably, Media Player in Vista, particularly, will often fail to play a video file completely, complaining that a “compatible codec could not be found.” Codec is short for COmpressor-DECompressor and is a programming algorithm (or method) for compressing and decompressing a digital stream. Such a stream may be audio, video, or both.
There are some additional applications that you can add to your PC to improve your ability to view downloaded video with different codecs.
