No - its an XBOX 360 remote.
I'm kinda pissed off because I checked here and what used to be www.thegreenbutton.com
and they posted the codes that worked for those remotes and their Vizio TVs The idea was to use XBOX as a media extender in the bedroom.
I don't have a full blown HTPC - i wanted to test out the CETON 4 channel card in a minimal config box and look into extenders - XBOX being the best of them. I thought I could kill off a remote in the bedroom and use the xbox remote cause it had the nice little Windows MCE button on it.
I'll look for an all in one remote and see what I come up with. I'm not moving my Harmony 1100 from the livingroom.
