PowerPoint 97 Issue with Windows 2000 Pr

We are currently using Office 97 with SP2 and Windows 2000 Professional SP2. We are having wierd problems running presentations, we have video in these presentations on some machines they work and on others they don’t, all the video files are linked properly with the presentation. I guess my question is… Is anyone else out there running into problems with PowerPoint 97 or Office 97 using 2000 Pro (SP2)

Thanks in advance
