Photo Slideshow - DVDMF or PictureShow?

[D2O]

I have done it both ways. I assummed that both produced 720X480 or somewhat less pictures in final product. DVD Moview Factory DVD took about 250 MB of 4.7 Gb available and Picture Show 1.5 GB. I read into this that Picture Show must be saving pictures in much better quality and size than does Movie Factory. But surely Picture Show does not put in the full size picture, or does it?

I would prefer to use Movie Factory as it allows the inclusion of Ulead DVD Player in the disc.

Which is better product overall for photo slideshows?
