OK, my understanding of "rendering" (vs CIA's definition of "rendering") 
is to improve the contrast quality or picture quality of a video; yours 
is to add a sound/audio track to an existing video track - spmething 
which avidemux should be able to do, I think because I have never used 
it for what you are trying to do.

I don't know, but only supsect, that the file you downloaded from the 
"internet archives" maybe the culprit to beging with. It may be using 
some sort of 'copyright protection'. How about telling us which is the 
file and the URL of the archive you downloaded the file from so that 
some of us could try it out.

I also think that you have undertaken a task which requires a bit of 
knowledge to do - ie, you cannot jump in head first into it. Have you 
done some research about this? There are some excellent HOWTOs on the 
web re this sort of thing.

The other thing, I agree with Ric: if you do have only 1GB of RAM then 
that is not really enough for your task. But having said this, even with 
this amount of RAM your computer should not suddenly stop in its tracks 
- it will slow down but not necessarily just stop. You either have bad 
RAM, or the CPU is overheating, or there is something about the archived 
video you downloaded. Seeing as how your friend with Windows also has 
the same trouble with this video, the same goes for his system. The 
question now is: what *is* causing your hassle? :-( .
