I haven't had much trouble with Toast 12.1 (except once when my iTunes directory was corrupted). I've made 4-5 Video DVD's with homemade material and YouTube material and have done just fine. Now it crashes after just 2-3 minutes, long before starting to burn - usually crashes when encoding. It will crash while encoding not just one certain file (I've substituted with no benefit). All my material is on a large partition (700GB-which is NOT on the boot disk). Has anyone else had a similar problem and solved it?
