Hi,

According this post:

http://windows.microsoft.com/en-US/skydrive/video-formats-supported-faq

We should be able to view videos in SkyDrive (on the web), but this does not seem to work. I have my Lumia 920 set to upload all photos and videos automatically over wifi and when attempting to play back these videos in the browser, nothing happens, I can only download the video. My phone is running GDR2 and I am using Internet Explorer 11 (from win8.1 preview).

The video formats are standard MP4 format that got created either by the default Camera app, or Nokia Pro Cam.

Must admit, I have not tested this using another browser.

Any ideas?
