Hi found Proshow, but it only outputs to cd type media.

How does it work to a dvd?
Does it create and mpegII file and then you author it to dvd an authoring program?
If so, when it encodes to mpeg II, does it degrade or change the quality of the pics? and will Proshow tell you how much space is needed for a particular slideshow, prior to converting to mpeg? thanks..t
