How do I convert a PC file to Mac form?

Google Video Player is another way to view Google videos; it runs on Microsoft Windows and Mac OS X. The Google Video Player renders files in Google's own Google Video File (.gvi) media format and supports playlists in "Google Video Pointer" (.gvp) format. When users download to their computers, the resulting file will be a small .gvp (pointer) file rather than a .gvi file. When run, the .gvp file will download a .gvi (movie) file to the user's default directory.
