True to very single positive review here in this list, this codec pack works like a charm. It has a very light footprint in the system and has no compatibility issues. As best practice, in general, when installing codecs, make sure there are no other third party codecs present. Ensure every trace is removed including the registry and resident files in the temp folder. If you already have another media player such as Winamp, Windows Media player 11, etc and you want to continue using the same player, make sure you uncheck the options to install the Media Player Classic during the installation. This is present in the list of decoders and filters shown during installation.
Thank you team for a clean, light weight, hassle free utility. After using almost all of the encoder packs available, this, by far is the most lean, clean and mean utility there is on the internet.
