I spent ages making a presentation on my Mac OS 10.5.8 in Office 2004, including an inserted video, only to open it on Windows Vista Home Basic in Office 2000 Premium and have the video not there. Instead was something about a decompressor. I did a compatibility report thingy on the Mac and followed the instructions about using a .avi file and saving as a Power Point Package. I opened it again on the PC only to find this time that there was a big white box with a big red X in the middle. I have hunted high and low for a solution to this problem, but I can't find anything. I can't insert a movie at all to Office 2000 otherwise I'd be doing that. Please please PLEASE can someone help me???
