Help me understand PowerPoint 2010 disabled options

The disabled options have me confused?

  1. Change the source file (from the original .avi you selected)
  2. Change the starting point (say start at 30 seconds)

I can see that those toolbar options are disabled (below) but I cannot see the reason.

Canvas and SVG – when will IE support it?

Clearly it is missing from Google’s presentation

Anybody think this is hurting IE’s market share?

Anybody consider this is solved, since we now have:

SVG Web’ is a JavaScript library at http://code.google.com/p/svgweb

Or

‘Google Chrome Frame’, an open source plug-in that brings Google Chrome’s JavaScript engine to Internet Explorer
