Quality Screen Captures To DVD

I am trying to produce some training videos on certain software programs and some websites. I need to get high quality screen captures that will look high quality once put on to DVD.

I've tried using Camtasia and I get good results if I put the screen capture on CD to be played on a computer but terrible results when put on a DVD and played back on a TV.

Has anyone been able to get high quality screen captures to DVD? If so could you please explain the tools and process that you use?

Thanks,
