Video encoding offers a great variety in compression and quality abilities, but can be cumbersome when it comes to playing video and audio on a computer.
The K-Lite Codecs Pack offers multiple “packages” of codecs for any level of media nerd. K-Lite is of course completely free and will not nag you to upgrade or pay. The basic pack includes codecs to play VI, MKV, MP4, FLV, MPEG, MOV, TS, M2TS, RMVB, OGM, WMV, 3GP, WEBM, FLAC, and Wavpack files. The “Standard”, “Full”, and “Mega” include more support and more software to help you play.
The “Basic” pack is 9.3MB, and the “Standard” back is about 13.7MB. Any software required to play media files will run automatically when needed and won’t waste your computer’s memory. K-Lite is also working on a 64-bit version, but that is still in the experimental phase.

If you are still having problems playing media, try out VLC as a media player. It seldom has issues playing video files and can also play sound.
