Hi there, I use cdrwin to back up ps2 games, with a YAMAHA F1 it works just fine. Underrun Protection works, burnt CD's work also. But now, with a MITSUMI CR-48XATE - there is just no go. Underrun Protection just can't be checked (grey button) as well as RAW MODE (also grey button, but is checked by default); the resulting CD's just don't work. Same Media, same Program, only different hardware. The Mitsumi uses the most actual Firmware (1.0G) i could find. Is this burner not supported by CDRWIN in some way? Any other Ideas? thanks.
