Fwd: Re: Very slow CD burning
Is cdrecord particularly conservative about CD quality?
I also have a burner that burns 8X in Windows, but only 4X in Linux. Is
there some way to force it to burn faster despite not having "high-speed" media?
BTW cdrecord reports "Disk sub type: Ultra High speed Rewritable media (2)"
below...
