If you want your slideshows to go to disc, you might want to try Nero Ultimate for DVDs &/or Blu-ray. there are sets of encoding settings or parameters for Blu-ray, some authoring apps will always re-encode if your video doesn't meet its requirements, and some players are pickier than others. You should be able to use Icecream Slideshow Maker Pro for Blu-ray too, using a similar workflow, & *might* get away with not having to re-encode, depending on the authoring app used & the player. Some DVD authoring apps will handle the re-encoding, & optionally burning for you, but unless you really like today's GOTD, you're likely better off creating the whole project in an authoring app & avoiding the re-encode. Icecream Slideshow Maker Pro isn't tailored to creating DVDs, though you should be able to create a slideshow, re-encode it to mpg2, then use a DVD authoring program, burning the results to DVD.
all main features are available in the Free version of Icecream Video Editor. Bearing in mind that many DVD players will display photos stored on a USB stick as a slideshow, with no work involved.
