hey guys. i registered just to give you this piece of information. this will make yahoo voice chat work:
FileForum | Vista Codec Package
please spread the word and help others with this info. also note that this codec package will enable you to watch all avi, flash, divx, etc. so you dont need to download any flash players or divx players or any of that crap. enjoy
also keep in mind that vista is a very well designed operating system and theres no need to fill it up with a bunch of crap. all the default stuff works great (firewall, spyware remover, etc). just get a nice antivirus and youre set.
