Hi, I have used the Movie Maker regularly and successfully. Today on trying to create a new movie I got the "spurious jmf data" message. Can anyone advise me how to overcome this? I attach a copy of the error messages bellow. Error messages: datasink open: IOException when creating RandomAccessFile C:\Users\Your%20PC\Documents\My%20Research\Documents\papers\YDS%20Poster15\images\Untitled.mov : java.io.FileNotFoundException: C:\Users\Your%20PC\Documents\My%20Research\Documents\papers\YDS%20Poster15\images\Untitled.nonstreamable.mov (The system cannot find the path specified) java.io.FileNotFoundException: C:\Users\Your%20PC\Documents\My%20Research\Documents\papers\YDS%20Poster15\images\Untitled.nonstreamable.mov (The system cannot find the path specified) at java.io.RandomAccessFile.open(Native Method) at java.io.RandomAccessFile.<init>(RandomAccessFile.java:243) at com.sun.media.datasink.file.Handler.open(Handler.java:303) at sim.util.media.MovieEncoder.setup(MovieEncoder.java:328) at sim.util.media.MovieEncoder.<init>(MovieEncoder.java:180) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:408) at sim.util.gui.MovieMaker.start(MovieMaker.java:153) at sim.util.gui.MovieMaker.start(MovieMaker.java:49) at sim.display.Display2D.startMovie(Display2D.java:1947) at sim.display.Display2D$10.actionPerformed(Display2D.java:1465) at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:2022) at javax.swing.AbstractButton$Handler.actionPerformed(AbstractButton.java:2346) at javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:402) at javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:259) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(BasicButtonListener.java:252) at java.awt.AWTEventMulticaster.mouseReleased(AWTEventMulticaster.java:289) at java.awt.Component.processMouseEvent(Component.java:6525) at javax.swing.JComponent.processMouseEvent(JComponent.java:3322) at java.awt.Component.processEvent(Component.java:6290) at java.awt.Container.processEvent(Container.java:2234) at java.awt.Component.dispatchEventImpl(Component.java:4881) at java.awt.Container.dispatchEventImpl(Container.java:2292) at java.awt.Component.dispatchEvent(Component.java:4703) at java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:4898) at java.awt.LightweightDispatcher.processMouseEvent(Container.java:4533) at java.awt.LightweightDispatcher.dispatchEvent(Container.java:4462) at java.awt.Container.dispatchEventImpl(Container.java:2278) at java.awt.Window.dispatchEventImpl(Window.java:2739) at java.awt.Component.dispatchEvent(Component.java:4703) at java.awt.EventQueue.dispatchEventImpl(EventQueue.java:751) at java.awt.EventQueue.access$500(EventQueue.java:97) at java.awt.EventQueue$3.run(EventQueue.java:702) at java.awt.EventQueue$3.run(EventQueue.java:696) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:75) at java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:86) at java.awt.EventQueue$4.run(EventQueue.java:724) at java.awt.EventQueue$4.run(EventQueue.java:722) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:75) at java.awt.EventQueue.dispatchEvent(EventQueue.java:721) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:201) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:116) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:105) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:101) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:93) at java.awt.EventDispatchThread.run(EventDispatchThread.java:82)
