Vista - Media Center problem

I have been looking on here before I posted, and it seems everyone has a similar problem! I recently installed TVersity.com and it was suppose to install some codecs for me to be able to play divix or avi's on the xbox but it crashed my setup now I cant stream anything to my TV. It seems Vista is good if you do not tweak anything or want to install things. I am getting a error 1068 Dependency service will not start?

When I open Media player it says my media sharing has been disabled? I cant find where it is disabled at, Well i just wanted to post my problem here also, I know you guys dont know the fix so I will continue to play, O,, also my System restore was off so i have no restore point , isn't that lovely!

ok I fixed it, all I did was go into Xbox360 dashboard and disconnect your connection to your Vista PC, now on the xbox go to the media center and get the setup key numbers, and then go to your vista PC and add extender through Media Center. Basicly I just started from scratch again and it worked!
