Finally got it to work. I added the .avi animation to both the diffuse and ambient nodes. Set the
color on both to white, and increased the value on the ambient from 0 upwards. 
Result is self illuminated animated tv screens. Appreciate all the help.

One thing though. when rendering it takes FORVER to render each frame. I never
use Poser 6 preferring the simplicity and ease of Poser 4 Pro Pack.
Is this normal for it to take so long to render.????
