Hi folks,
just a hint - I had much trouble in converting Powerpoints to flash with adequate quality in the same context (viewing more than one PPT on a MagicInfo screen). Last week I came across the free beta version of Office 2010 from Microsoft, with the new PowerPoint 2010 (download from Microsoft's web site, will run free of charge for several months). There is a new option in Powerpoint 2010 - save presentation to Windows Media File (wmf). This creates a video file from your PPT presentation with all transitions, animations, sound, etc. in a very high quality. And the wmv file is fully scalable on the MagicInfo screens. Files are a little bit large, depending on the number of animations / transition effects, but the quality of the presentation is extraordinarily high - much better than everything we saw before with PPT to Flash converters. And yes, it allows you to run several presentations in parallel on the MagicInfo screen. We do that now for all our screens and do not use flash videos anymore. No separate viewer is required on the displays, it runs with the (current) standard configuration of MagicInfo Pro.
Sincerely
Gerald
