I am trying to zip some .movs with ZipIt 1.5.3, that will be put on my web page. The .movs are self-contained flattened Quicktime .movs which can be played by both Mac and Windows users. Unzipped, the .movs play without any problems. However, when I zip them, they can only be opened by Mac users. Why is this? I have set the default compression at deflation, and have checked the never use macbinary box. Is there something else I have missed?
