I have just upgraded from DVD Architect Studio 4.0 to 4.5c. Now when I attempt to burn a DVD+R (any brand) on my Plextor drive, the burning Lead Out takes about 4minutes compared to 20 seconds under 4.0. The burn does complete, but the DVD will not play. DVD-R media works just fine. If I go back to version 4.0, I can burn the DVD+R media. Tech support has not responded. Any ideas out there?
