Hello kseannng. Shark007's FREE Codec solutions.
This place is good for Vista but is not so good on Seven. With Seven some blu ray movies work with sound and video but others work only with sound, you would also have to use AnyHDdvd to play the blu ray movie with in WMP. With Seven and or WMP 12 all movies play in another language instead of english.
Within Vista, all movies played in english having both video and and audio. My current method at the moment is dual boot Seven with Vista. I will be testing XP mode with AnyHDdvd, Shark 007 codecs and WMP11 combined.
