Have you updated to the latest build of MediaShout 7? www.mediashout.com/download
I brought that .PPTX file into MediaShout 7 as a Presentation and it converted it pretty nicely. Slide #7 had the biggest issue where that Timeline graphic did not get carried over. The good thing about bringing it in this way, it is all editable within MediaShout now. So you can add that graphic in on that slide and adjust it, as needed. All of the other pages looked really nice. Page 10 & 12 I had to make the text box bigger to fit all of the text, but that was really it.
Are you seeing something more than this?
There are a couple things here and there that they will continue to work on to make that better and better. But, we are really happy with the way it is currently working.
I hope this helps!
