also if you can find a format (.3DS,.Obj...etc) to import your consoles into poser, so that  the screen itself is a seperately selectable material zone, then you can apply the above tutorial to just the screen, leaving you able to texture the rest of the console (sides, panel, buttons..etc...) as you wish.

if you can't get it in with seperate material zones then i would do this:

in your modelling app (if you still can do this) remove the screen area, and save it as a seperate object, and save your screenless console aswell ( the console you would have to make a uv map and texture that seperately) , then bring both objects into poser, position the screen to where it is supposed to be on the console, then parent the screen to the console, now if you do the above tut, applying that tut to just the screen, you will end up with your console with a uv map texture, and a screen that is animating the .avi. 

if you want glow from that screen though then that another story (LOL) but also possible.

hope that lot helps ya.
