Pardon me if this is not the corect forum for this question. I currently have an external 5.25 DVD optical drive which is faster than my fist generation iMac's burner. I'm looking into replacing the internals of the external enclosure with an NEC 3550A capable of burning dual-layer disks; it already has an earlier NEC optical drive. My question is this: Will any version of Toast Titanium burn to a DVD DL, or do I need a specific version, or software? Will Toast recognize the capacity of a DL disk (with a DL drive) and record to it? I can find a lot of information on the optical drives themselves, but not a whole lot on how to utilize them. I currently use Toast 5.2.3; a bit antiquated, but it works for now.
