Media Player Codec Pack is a codec collection that helps you deal with any multimedia file, be it video or audio, without the need of installing additional software.
The most important step when it comes to the way the codec pack works is the installer, because it empowers you to pick the components you wish to deploy on your computer.
Be careful though, as the setup kit also comes with some additional tools that may bring a number of changes on your computer. That's actually the reason why Media Player Codec Pack is flagged as ad-supported here on Softpedia.
There are two installation modes, easy and detailed; we recommend that you pick the latter because it also enables you to skip the installation of the aforementioned unnecessary tools.
The setup kit includes a third-party toolbar plus a dedicated option to change the homepage and the default search engine of your browser, so pay attention to every single step.
As for the codec package alone, it includes DVD/SVCD and DVB filters, video codecs and filters, such as ffdshow, LAV, XviD Encoder and Flash FLV, audio codecs and filters (AC3Filter, LAV Audio, DivX Audio and Lame MP3), plus a collection of other source splitters and filters.
Last but not least, Media Player Codec Pack provides you with the possibility to configure file associations straight from the installer, which means you can set Windows Media Player to handle MKV, VOB, FLV, FLAC, OGG and a bunch of other files by default.
As a conclusion, Media Player Codec Pack is a decent codec collection that does its job just fine. It is worth a try, that's for sure.
