Unfortunately, Star Office doesn't support any video format. From what it seems, you opened another file type instead of the MOV file. The application has been developed by Sun Microsystems to work only with .sdw, .sxw, .odt, .ott, .sdc, .sxc, .ods, .ots, .sdd, .sxi, .odp, .otp, .sda, .sxd, .odg, .otg, .sdb, .odb, .smf, .sxm, and .odf files.
