I am experiencing the same issue described here since I upgraded to Jaunty (not in Intrepid).
I am using Kubuntu 9.04 and the Kaffeine installed version is 0.8.7-1ubuntu5.
I have also realised that DPMS power saving options are also not disabled while playing a video (that means, monitor will stand-by as if no action was going on when watching video). This was also working fine on Intrepid before upgrading.
Finally, I have the same issue if the video playback is done using Mplayer or Xine.
I can provide other necessary info (logs, traces) if requested to me.
