First off, I apologize if this was covered previous somewhere on the forums.
When Toast counts down minutes and seconds until the burn is complete, the seconds take about 4 seconds between single digit decrements.
I have been using only store bought versions of Toast 5 and now 8 and have been getting the same slowness problem. When burning about 4GB of data to a DVD, the disc is recognized as 8x (actual media is Memorex DVD-R), but it can really only sustain about 2.5x. My machines are all stock Macs (older G4 Tower MDD, new Mini, and new iMac) all with stock SuperDrives of at least 4x and the iMac is 16x DL (IIRC)!. I'm NOT copying VIDEO_TS folders, so that is not an issue. The data, if anyone thinks it matters, are segments of disk images of home directories made via Disk Utility (make new image from folder). No other applications are running and the processor load is very low. Harddisk is also low load.
I don't think it is Toast, the machine, the DVD burner, or the data. Toast reports the media is capable of the higher speeds. My understanding of DVD burning is that once the drive starts to burn, there is no verification which the burn is happening. So the issue would need to be either bandwidth issues with the burner, processor, or harddrive, and I just don't see it.
The only thing I didn't try, which I realized as I typed this, is that I specified underrun protection. Would that actually slow things down? I thought that was a burner feature that if the buffers emptied, the drive slows down, or writes no-ops to the disc, until the buffer is replenished....
Any pointers would help, but I don't want to mod my drives firmware. Everything is stock on the new computers, so it *should* work...
