This didn't work for me for the chase scene and it wasn't necessary for the Shadow Broker DLC. It will work for some but not all. It got me through the Kasumi Goto mission. What I finally did was create the ME2Game shortcut then I right clicked on the shortcut. From there:
Properties>compatibility>run this program in compatibility mode
Then in the drop down menu I selected Windows 7. This worked for me and I was able to use all the graphics enhancements I wanted without any crash. I even removed " -nomoviestartup" from the target and it still ran perfectly well. IDK, might help if the crash continues.
