It seems that Presenter 09
only supports the default page setup in PowerPoint which is
On-screenShow(4:3). See this article. However, we use several ppt templates that use a 16:9 aspect ratio, and we'd like to be able to produce playback files in 16:9 aspect ratios, for delivery on YouTube as well as for better playback on modern HD monitors. Any plans for this in the next release of Studio?
