Your talking about the Combined Codec Community Pack. Well yes, I use it and I believe Budweineken uses it to. Both of us listed what codecs it has listed in kAi's Codec thread. I haven't had any problems playing any of my anime with this pack. I highly recommend it to everyone since all the codecs are organized and you don't have any unnecessary codecs that you might've installed before. Its not that hard to download either. Just go to link listed by either me or Budweineken and install it. It also comes with two players, Media Player Classic and Zoom Player. I didn't install Zoom Player, I went with Media Player Classic but the cccp still works great with just Windows Media Player to.
