Keep getting a reproducible crash in my DO install:
Microsoft Visual C++ Runtime Library
Runtime Error!
Program: C:\Program Files\GPSoftware\Directory Opus\dopus.exe
R6025
- pure virtual function call
OK
Basically, I click a MP4 file (I can't provide the file as a sample, sorry - best I can do is to see if I can find another MP4 that it crashes on that I can provide), hit F7 to open the viewer pane, then when it starts to play, hit F7 again to close the pane. At this point, I notice that Haali's Media Splitter - which I have installed and which DO starts up when it plays the file - is still in the system tray. Double clicking the Haali's tray icon, DO immediately crashes, pops up that error dialog, pops up the Windows 'Directory Opus has stopped working' error dialog after that, and then restarts (well, one time it did not automatically restart as it had done all the previous times, it just popped up a dialog telling me I would need to restart DO myself). This is from Windows problem reports if it is helpful:

Haali's is just a DirectShow splitter (and optional video renderer), so DO uses DirectShow to open the MP4 file, and then presumably, it all goes wrong somewhere after that.
