Fig. 2 Screen capture of error message in PowerPoint 2002 (Windows
XP Professional, both Microsoft) when displaying movie clip without proper
codec. In this example, movie clip was saved in AVI (Audio Video Interleave)
format and was inserted into PowerPoint previously using Ligos Indeo R4.4
codec. However, this codec is no longer available in Windows XP operating
systems. Similar error messages will appear when any invalid movie clip
attempts to display during PowerPoint presentation.
