Here's the code:

#declare screen = concat("filename",str(frame,-3,0),".png")

where "frame" is a counter tied to the clock variable so that it increments
once for each frame rendered.  This gives "screen" the value
"fliename###.png" where the ### is incremented each frame.  The -3,0 forces
"screen" to have three numbers (and no decimal places).  You can use any
sequence of frames with any filetype POV recognizes. Now if you can only
finde some sequentially-numbered files :) you'll be all set.

Then:

pigment { image_map { png screen }
     translate <width/2, -height/2, 0>
}

so the image "screen" is mapped to the TV screen (width and height are
variables in my TV macro).

That's it!
