VirtualDub is a great and free video capture and editing open source utility. However the author announces that he won't support DivX 5.1 in any way, shape or form in VirtualDub. It's not that he is boycotting it, its just that after he installed the codecs and tried to play something he was greeted with the message: "Debugger detected - please close down and restart" - A userspace driver (even the free version) with a protection wrapper. He can't debug Virtualdub AT ALL when the codec is installed because it triggers on load, in fact you can't debug any programs if you hover over an avi in the open dialog, explorer load the codecs to dislay information and the codecs terminates your application.
He does not this is a good choice on the part of Divx Networks, I agree!
