Can burn only DVD+R/W disks all others eject with media not recognized. 321Studio support has ask about 5 times who makes the disks among others was SONY. Would like to be able to burn -R, +R, and -R/W. THe burner is capable but DVDXCOPY is not for me. Have attempted to work with 321Studio up to an Assistant Manager. What a waste of time Thanks for any info.
