Help with .tgz format

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I retrieved the Gatos drivers to allow me to do video capture with my ATI card. one of the files is km-0.2.1.tgz. I *THOUGHT* the .tgz meant that it was a gzipped tar file. So I issued the following: tar -xvzf km-0.2.1.tgz In return I got the following error message: gzip: stdin: not in gzip format tar: Child returned status 1 tar: Error exit delayed from previous errors How can I unpack the file. It shouldn't matter at all with tar, but I'm running 8.2 if you think it does. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2-rc1-SuSE (GNU/Linux) iD8DBQE+z47bjeziQOokQnARAqzrAJ9VEN6cZIEwlDnyLJQB31OA13iF2QCgjnxv dE8dyvZKOoP03jZfholkvsQ= =/ngG -----END PGP SIGNATURE-----
