Please provide any information that could help me run QTO for 20 minutes without it crashing. Currently I am running Win7 with an Intel Core i7-2600 CPU @ 3.4GHz with 4gb RAM. Video card is NVIDIA GeForce GT220. Hardware accelerators are also turned on inside QTO settings.
I have recently heard that .dwf files vs dwfx files were recommended for QTO 2012. QTO 2013 should fix some crashing associated with .dwfx file format.
