Sometimes the web videos, and the "get started" video work.
Other times, is black, or green, saying video has failed.
We both have the same problem. Something I can't figure out.
On a clean install, videos work without flash installed.
As I added VLC, and Irfanview, video stopped.
Downloaded Adobe flash, no difference, no video.
Clicking halfway through video makes it work again.
A wee bit frustrating.
