Tested last night with cdrtools a77 version on sun ultra 60 with solaris 10
The work-around allowed me to burn a 7 GB image to blu-ray disc
but it took over 2 hours, seemingly as slow as growisofs on that machine
How do I get cdrecord to burn at 2x speed?

# cdrecord -v dev=4,0,0 speed=2 driveropts=burnfree image.iso
cdrecord: No write mode specified.
cdrecord: Assuming -sao mode.
cdrecord: If your drive does not accept -sao, try -tao.
cdrecord: Future versions of cdrecord may have different drive dependent
defaults.
