I’ve been able to play one MP4 video on the PC per boot of windows. Every subsequent time it crashed. It turns out that the intervideo mp4 video decoder was at fault. It was preventing me from enjoying the stalker trailer that gleb pointed me to.
The Solution? unregister the intervideo mp4 decoder.
How do I do that? pop up a command prompt using the run dialog, on the drive that you installed the intervideo software cd to \Program Files\InterVideo\Common\Bin. At the prompt type: regsvr32 /u MP4VDEC.ax, and it all works job oxo.
If it wasn't for carbon-14, I wouldn't date at all
