A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
I am also working in radiology and ran into the same problem recently when I had to present on a small meeting. Naively I assumed that Powerpoint 2013 must be superior to 2010 (both products are installed in their 32-bit version on my Lenovo Ideapad 13), but then NONE of the videos worked under my presentation. Powerpoint 2013 made me look like an idiot.
Now I am preparing my next talk for an international meeting. As a matter of policy, I only use uncompressed avi-files for my videos, uncompressed, so that they can be shown on any meeting on any equipment - but no, Powerpoint 2013 does not show any avi. I had to go back to Office 2010 and everything works like a charm.
I must say, I am very disappointed indeed. This bug must be fixed!
