Our marketing team made a presentation in Powerpoint 2007 (saved backwards) including various video clips (.WMV) for our sales force. All our operating systems involved are Windows XPsp2, we use Office 2000 products all at the same build level. The sales force immediately reported back that some videos were freezing whilst the audio carried on. Not all users just some. Not all videos just some but those that had this problem it was a 100% certain problem, consistently everytime with "that video". The presentation was re-done from scratch in Powerpoint 2000 and the results experienced were the same.
Investigation showed that when opening in WMP11 the video codec in use was either Windows Media Video 9 or Windows Media Video V8 depending on the file in question. We found that across all laptops that whilst opening the file from WMP11 all files worked on all the clients, using mplayer2.exe all files ran fine on all clients, but using mplay32.exe certain machines the WMV9Codec video files would not work but the WMVv8 would still work (audio would play but video would freeze up or remain black).
The select files that the select clients had trouble with whilst in Powerpoint & mplay32.exe were the "WMV9Codec" ones, WMVv8Codec ran fine on all machines, all applications.
Further investigation showed that all the machines with this problem are Toshiba laptops and all use the Intel 965 Express Chipset which has an integrated display adaptor i think is Intel® GMA X3100.
From the manufacture website we checked we have the latest Toshiba drivers (6.14.0010.4814), even though it appears Intel have released a more recent item (6.14.0010.4980) which won't install on the Toshiba via .exe or device manager "update drivers"
To enable the problematic videos to be on these problematic machines in either mplay32.exe or Powerpoint 2000 we have disabled video acceleration entirely and all runs well.
Anyone able to shed light on why we are getting problems with these certain files, applications and harware co-existing ?
