While that patch will prevent the crash you were seeing, it introduces a 
new bug--a race condition that could cause problems if you use the 
MythMusic "embedded player" (i.e. leave music playing when you exit the 
MythMusic plugin) and then switch to video playback,  Paul described in 
http://code.mythtv.org/trac/ticket/9819#comment:3 .

So, as long as you don't use the MythMusic embedded player on your 
Windows system, or you're very careful not to trigger the issue, feel 
free to use the patch on your Windows build until someone works out a 
proper patch.
