Hello,
We are using CS 5.5 on Windows 7 x64. Our videos are exported using the H.264 format.
The problem is:
We can embed the video in powerpoint (assumed quicktime is installed) but when we want to play it in the presentation, it simply shows a black screen, audio works. The weird think now is, when I fast-forward for at least one time, it works. It only shows a blackscreen if you dont fast-forward for atleast one time.
The problem could be solved, by installing the k-lite codec pack, but since we are sending presentations to other people, outside of our company, this isnt a solution.
I checked it on Windows 7 x64 and x86 with office 32 bit and quicktime, I get always the same result.
Anyone else having trouble to get their H.264 exported videos working in powerpoint 2010?
Thanks in advance 
Malte
