Lightroom 4 & Slideshow Presentations

As a relatively new Lightroom user, I have become very disenchanted with Apple's iMovie '11(with which I am quite familiar). The image quality of the photos that I post-processed in LR4 were seriously degraded after importation into iMovie (specifically, tonality changes & general color shifts). Hence, I am looking for a high-quality slideshow presentation application that will retain the integrity of my processed images.

Regrettably, the slideshow module in LR4 lacks both the abilities to sync images to a playlist & to burn directly to a DVD. Therefore, I am looking for alternatives.

FotoMagico Pro as caught my eye. It appears to be Mac-compatible & full-featured for my use. However, two questions arise:

(1) Is ForoMagico Pro seamlessly integrated with LR4?

(2) Is image quality retained after importation into FotoMagico Pro?

Thank you for any help you can provide. Also, I am certainly open to exploring any other slideshow apps that you might recommend. Much appreciated!
