Why not create your slideshow in iMovie and use the 'Ken Burns' effect.
However, if what you mean is the ability to zoom in on an image while a DVD is being played back the answer is probably no - it depends on the features your TV set might have. (Some TV set offer a zoom function.)
My TV set/s do not offer any Zoom function at all but all of our set top DVD Players do (via the remote control/s). It's clearly labeled on the remote as "Zoom" or Zoom In / Zoom Out.
