supercat,
What's you point?
MTU said: "We can't certify anything for any other drives".
What do you think they're talking about? Do you think they're certifying how to do R&D on CD burners? Do you think they want to certify a new standard for error detection and correction for CD burners to handle CDG graphics?
Of course not, they are trying to certify which manufacturers models "in existence" are compatible with their software to save their customer from having problems.
You're missing the point of this thread by confusing yourself with Yamaha's marketing hype.
You said: "a misread in the graphics subcode data will cause a glitch to appear on the screen".
I'm not having problems with glitches on the screen and audio dropouts. Are you supercat? If not, what IS you point?
