this is rumour control here are the facts: win7 product keys are only usable once and i moved an lost mine and when i had to do a system rebuild on my pc as i built it initially i didn't have the key to use for the reinstall,so that is why i used vista home premium and whenever i have my pc on now and the xbox gets turned on so one of my kids can play,i get a window open on my pc saying install correct driver which then precedes to not actually load the driver,so what i am asking for is that some one be able to point me in the right direction as to where i might possibly be able to find the right driver to resolve this issue,the driver allows me to use the xbox video player to watch movies that are on my pc,yes i know media centre is on there as well but certain films won't play on windows media centre,predominantly MKV files,and in all honesty i have never had any issues with vista being problematic as I also have it installed onto my laptop.
