99% of the old image CD's open fine on the Mac . . . then there are those which open titled: "UDFREADER" . . . clicking on that brings up three files: "Autorun.inf" "UdfrChk.exe" & "udfrinst.zl" . . . these problem CDs were burned on a Windoze machine & most likely with an external Sony firedrive burner which came with an odd burning program . . . . . . . anyhow . . . . . . . does anyone know of a way around the autorun other than reburning the offending CDs on a Windoze machine ?
