Changing Background Color in Output

[hitek]

How does one change the background color in all of these outputs?

• MMP - Everything behind (or maybe around) my images is gray.
• Silverlight - Everything behind (or maybe around) my images is white.

I would think there must be some approach in the styles.

Also, can I direct the output to a different folder. I want to create two versions of the output.

• Auto Timing
• Pause at the end of each slide, forcing the presenter to press next.
