The following is an exchange I just had with Roxio tech support. I have a new iMac with 10.5.6 installed so I can't revert to an earlier version. A week ago I had the same type problem with toast version 7. Any suggestions? Thanks. Me: I just installed an version 10 upgrade from version 8. I copied a CD onto Titanium 10 and then inserted a blank CD to make a copy and got the following: "Interface Error:-32030 The connection is not stable". What happened? What should I do? roxio tech support: Have you installed Mac OS X updates? It is being reported that issues similar to yours are happening to users in similar conditions using Mac OS X 10.5.6 Please remove last updates or use the Time Machine to revert to a period prior to the latest Mac updates Me: I have a 2 week old iMac with OS 10.5.6 installed. So there has been no update from a previous OS. Now what? This happened with my Toast Titanium 8 and I was told to upgrade. Are you working on a fix? tech support: Please contact apple as this is a hardware related issue. I contacted Apple which says it's a Toast issue, not Apple. Sigh.
