I am trying to insert an MPEG-2 movie into my PowerPoint 2010 presentation. It plays fine in the Windows Media Player on this computer, and the equivalent AVI movie inserts no problem, but the MPEG-2 shows up with haphazard green squares instead of the correct picture, although during playback the correct melody sounds.
I prefer MPEG-2 to AVI since it takes 16 Mb instead of 600 Mb...
Thank you very much.
