OK. In Openshot I loaded up the 466.6MB AVI and I added a sound track;
I'm am exporting to DV NTSC now. I can see in 'top' and the cpu monitor
that the export is taking 75-95% of my CPU (2.4Ghz single core). I see
the temp of my processor going from 40C to 51C... ooops now at 52C. I
have set my temp sensors to alarm at 70C & could probably wait to see if
it gets that high... however I'll kill the process if the temp gets to 58C.

I very much suspect that you are getting a thermal shutdown. Many BIOS'
will have a crash log & a thermal shutdown will show there. A thermal
shutdown won't show in the OS logs, so check your BIOS logs.

Were I you, I'd install temprature sensors & watch the temp of your CPU
when exporting. You can also try setting the process to a 'nice' value
or 10 or 15 so that it takes less processor priority. You can do that
from the System Monitor applet, or from the command line:
