I continuously get a crash, complete and immediate shut down of my computer during rendering of mpeg2 files. It usually happens between 2 and 5 minutes into the process. I am using an HP AMD 9550Quad processor with 8 gb ram 64 bit system and Windows Vista home premium. I have tried many suggestions from forums and none have been successful. My problem reports and solutions states that is is a program compatibility problem. HELP!.
