Help With Tweening

Hey Guys, Im new to this forum so i dont know if anybody has ever posted on this topic before (people probably have).

I have just created an Electronic Brochure for a client using Flash MX 2004. In it I have used motion tween to fade from 1 image to the next. On my Machine it displays perfectly, however on the Clients machine it give a slight lag and a “Shuddering effect”.

My questions are:

  1. Is it his graphics card or Ram?
  2. Is there any code that I can insert to solves this?

Please HELP!

Shot guys.
