Any idea why Powerpoint changes my font weights and cuts? (Not defaulting out)

Hello Typophiles,

I am currently building a few powerpoint presentations for one of our clients, and have encountered an odd font issue. I'm hoping that someone in this forum can provide some suggestions for a fix.

I am using MetaPlus for my designs. I've noticed that when MetaPlus Medium is placed in powerpoint, it is significantly thicker (more bold / black) than the same font when displayed in Illustrator or Photoshop. In addition, some of the Roman cuts are displaying as italics.

Has anyone experienced this problem, or more importantly - can this be corrected, or is it yet another sad fact of powerpoint!? Thanks.
