As Cosmo says but this may only solve it for the current presentations. You need to mess with the registry for a total fix OR maybe try changing the setting to 220 dpi.
If you are happy working in the registry
Create (or alter the value) of a key
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\P owerPoint\Options\AutomaticPictureCompressionDefau lt
Set value to zero
Don't do this unless you know what you are doing!
