Why does preparing a burn of about 50k files to a DVD in "Mac & PC" mode take way over 15 minutes? With preparing, I mean the time between the end of the "Verifying 50.xxx files" stage and the "Filling RAM cache" stage. The preparation stage of a burn of the same same set of files in "Mac only" mode is finished in roughly 7 seconds.

I have burned several DVDs with a similar amount of files in "Mac & PC" mode with earlier (pre-7) versions of Toast and cannot remember it taking anywhere near as long as now. Has this changed with Toast 7? Is there any way to speed up preparing a "Mac & PC" data DVD burn significantly?

During the preparation stage in "Mac & PC" mode, doing a Sample in Activity monitor shows very deep traces similar to this little excerpt (Toast also takes all the available CPU time in this stage):

Does this ring a bell on anyone what might be going wrong here? Does anyone else have this problem? Or a solution?

Toast 7.0.2 behaves the same. Toast is generating the file system for the disc. It takes longer to generate the ISO.

180 times longer? I really hope this can be optimized to the speed I seem to remember earlier versions (5.x, 6.x) of Toast had (how did they do it there?).

Thanks anyway,
