There are many topics on many forums and sites about which codec packs should you install, and the debates that go along with it. There was quite a long topic here on this forum as well. A long while ago I used to use K-Lite Codec pack but always felt like it was bulky and full of crap, and I don't remember what got me to change but for a very long time now I have been using CCCP for my media usage. Recently they have slowed down, even stopped updating the software and I have was having issues playing some of my files. So I have switched to Sharks007 codec pack, but I am unsure how good it is at the moment. I have also tried just using VLC to play my content, among other players and they never are able to play everything. So now I am about to do a fresh format and install of Windows 7 and I am thinking about just installing the separate codecs that I need. I want to use Media Player Classic Home Cinema to view my content. What I am wondering is which codecs you NEED to watch basically anything. I am pretty sure FFDShow is one of them, do you need anything more then that? Or is this question more opinion just like the packs? Or is there another codec pack out there someone would recommend? ** Similar related question, is there any free blu-ray playing software out there yet? And why is it taking so long for that to happen, was it not much quicker for DVDs?
