I tried to create a stop frame animation in PowerPoint 2010 by saving an imported photo album as a WMV file. This is available when run on a Windows OS but greyed out on the office crossover bottle version of my office installation.
The following 2 approaches were tried to resolve it, with the 2nd being successful:
1) I first tried to install Windows Media Player v11 in my office bottle having logged on to the MS website via a virtual OS to prove I have a genuine license so that I could download it. However after downloading and trying to install the exe in the office crossover bottle, it tries to verify is it being accessed via a genuine OS, so failed to complete the install.
2) On second attempt I searched Crossover for 'media' and found 'Windows Media Encoder 9 Series' and installed this in the Office bottle. This allowed PowerPoint 2010 to encode the WMV file which ran brilliantly in VLC.
Useful for an budding animators out there...
Not sure if this helps running media clips within presentations, but the CodeWeavers team should contemplate including this additional encoder as standard when office bottles are built in future.
