[ms office - 2003] Powerpoint 2003 video issue

[sippo]

We have an intermittent fault here for our year 11 students. We are still running XP Pro with Office 2003. (planned upgrade in the summer).

 

Anyhow, when they try to install a .wmv file it sometimes runs and sometimes it doesn't. For example, a student will have the video on their home drive so will have full permissions. When they insert the video, it will work. So they save the powerpoint. If they log off, and then back in the video won't run. No error messages. Flash is all upto date as is java. It really has stumped me. I thought I fixed it a few weeks ago, as the head of ICT said it was working. So was working for a couple of months, then it didn't work yesterday. Nothing has changed on the network.
