I've just successfully burned two DVDs at once on the same Mac -- something that might be of interest to people who have two DVD or CD burners. I have a laptop with an internal Matshita DVD-R UJ825, and an external Pioneer DVR-108 in a Firewire enclosure. Here's how I did it:
- Simply duplicate the "Toast 6 Titanium" application (cmd-D) and rename it to something like "Toast 6 Titanium 2."
- Launch both copies of Toast, one after the other.
- Ensure each copy has selected a different DVD burner. You can toggle the selection by clicking the name of the burner at the bottom of the window.
- Burn as normal! eg. Drop one or set of data (eg. VIDEO_TS folder) onto one running copy of Toast and something else onto the other copy of Toast.
This technique burned and verified both discs OK for me. The only catch might be the speed of the hard drive in keeping up if you try this with two fast burners. Two 8X burners gives you a 16X effective burn, which is about 22MB/sec. This should be OK for an internal drive or FW800, but might be too much for an external FW400. Two burners running at 16X is 32X effective, or 44MB, which is probably too much for anything other than an internal hard drive. But getting sustained 16X is fantasy land at the moment anyway, let alone real 8X...
