Unfortunately, none of the programs mentioned - >which ID- canplay the file in question If the file was really an MPEG file, then QuickTime would have been able to play it just fine. It is either not an MPEG file, or it is corrupted, or something else. You might want to try dragging it over Stuffit Expander to see if it is still encoded or compressed: You can download a free copy of Stuffit Expander from: http://www.stuffit.com/mac/expander/index.html Then you can try playing it with QuickTime again. And if that fails, you can try VideoLan Client to see if it is another file format. If none of these work, then I suspect that your chances of viewing the file are bleak. Randy B.
