Multicast or something like it

I have 3 WDTV Lives and would love to be watching the same video as I walk from room to room.

Has anyone figured out a way to do this?

And no, I don’t want to try to start the video on each player and FF and REW to sync them up!

TIA 

Hello,

so, let me see if I got this right. You want to play the same video on several TV’s?

Correct! I’ve got a WDTV Live on the TV in the bedroom, one in the kitchen and one in the livingroom. I would like to have the same video playing on those 3 TVs at the same time. 

I can set up a streaming multicast in VLC on one of my PCs and watch it on any other PC in the house.

I would love to be able to subscribe to that multicast with my media players as well.
