After several years DVD burning on PC and Mac, I had my first 'coaster' (buffer underrun) the other day with Toast. This was surprising, since I have almost never had any of these, and was under the impression that modern drives have buffers to prevent precisely this from happening while multi-tasking.

I have burned two DVDs today, and Toast crashed both times. I store the data in a compressed mac-only disc image in Toast to get compression, and then save it onto a DVD readable by both Mac and PC. This usually works.

Both times, it seems to have crashed seriously enough to make me log out. (it gets to the end of writing the disc (reports: writing, and 00 seconds to go, and then refuses to respond, even to force-quit or kill -9 pid). Also, something is happening with the drive all this time, because when I put my hand on the casing (it's external), something is going, whether it's the drive mechanism or fan.

This is the sort of uncivilised behaviour modern OSs are suppsed to sort out...

When I then log-in and run Toast, it can't see the external burner until I quit and run Toast again. Then it sees the burner, and Finder can find the data on the disc as well.

I used to love my Toast. Sigh.

Are these dvds valid? Does it mean the disc wasn't finalised/closed? How can I stop this happening again?

Am using Toast 7.0 on the principle that I try not to upgrade things early: 'if it ain't broke don't fix it'. Am beginning to wonder if 7.1 is a necessary bug-fix release that would solve this quite annoying problem.
