DVD-Profiler 3.5.1 worked well here with Crossover 7.0.0 and 7.0.1.
But since update to Crossover 8.0.1 the DVD-Profiler crashes with errors in xul.dll or js3250.dll ("Exception EAccessViolation") directly after the main windows appears. Sometimes it works well for a few minutes and then it crashs with same error.
Both (Profiler and Crossover) deinstalled and reinstalled: Same error.
