fobs4jmf.dll Error in Java Swing playing .avi videos

I recently started helping a colleague with debugging a video crash issue with her Java Swing application. The application makes a native call to fobs4jmf.dll for playing .avi files. Sometimes, not always, the native code crashes the application. I didn't write the original application and the engineer that did is long gone; could anyone provide some insight? The error file is as follows:

The error apparently first came about when her systems were migrated to Windows 7 from Windows XP (you may begin cursing silently and shaking your hand at IT departments everywhere); but reverting the machines back to Windows XP didn't fix the problem.

It is also worth reiterating that this error doesn't always occur! Sometimes the application runs fine and sometimes it crashes when starting the native JMF code.

Thanks for any help!

such error generally occurs when system don't have dll file support, so try to check dll support for your corresponding player or

download any application which fills the necessary dll files in your system try
