I use a PowerPC G5 Dual 2Ghz 3GB SDRAM, OSX 10.5.8 Leopard with a Samsung TSSTcorp CDDVDW SH-S222L disc burner. I burn a one-track music CD with Waveburner 1.5.2, and have defined an ISRC-code on the track. But checking afterwards a strange ISRC is displayed on this computer when I use the Terminal.app command "drutil subchannel". (Toast "Disc information" gives the same result.) Using the same procedure on a MacBook, however, (with OSX 10.6 Snow Leopard) the code shows up correctly, from the same CD, which should prove that the initial burning sequence was correct. Example: The correct input code is NO2M41001010but the code that erroneously shows up on the PowerPC is strangely enough Co2M21001010. (Notice the correct "2M", the non-standard lower-case "o" and that the last seven digits are correct!) I have burned several CDs and tried different settings in Waveburner and the erroneous number is always repeated on the G5 (but always shows correctly on the MacBook)! So what's going on? I was told by the Apple representative that I should reinstall Logic Pro 8 (because I had installed the Snow Leopard more recently than Logic. That advice does not seem convincing. Why should Logic influence the Terminal.app? (And by the way a tedious procedure). Samsung support technicians say I must talk to Apple about about itbut Apple support has given me no clue so far. Any ideas?
