Nope.
The Panasonic (DVC50, DVCPro HD, Etc.)codecs are licensed to Apple for use in FCP and usually not available on a Windows machine without purchasing the Codecs separately (fairly expensive). If it’s just for approval, export a DV25 (or, oddly enough, a DVCPro25) file and they should be able to play it on their machine. It will export pretty quickly as well.Otherwise, use a different Quicktime file format. Sorenson 3 is fairly quick and can be played on a Windows machine with Quicktime installed.
