The Samsung Magicinfo screens now days have both Magicinfo Pro and Magicinfo I installed. You need to select one or the other, but I think they can both co-exist although one running at a time.
Magicinfo Pro is the most used one at the moment and I can see Magicinfo I surpassing it at some stage. Magicinfo Pro is a server-client based scenario. With Magicinfo I you have three elements Authoring, Web Server and Client. The Clinet is easy, just waiting (just like Magicinfo Pro) to accept media files. All the templates are compiled on the Authoring software, then you upload them to the Web Server (based on TomCat web server). At the server side you have the scheduling to do and also managing of the screens.
I am using both - I find Magicinfo Pro perfectly OK with what I do, however, for enterprise work, I'd choose Magicinfo I. If you are in the UK, Samsung do have the Training once a month free of charge. Their website is: www.partnersamsung.com
