Well, the max trace level I'd need to show that bit correctly would be at 
most 6, and my max trace is currently 80!

The problem seems to simply be I have 2 different media-containers that 
happen to overlap, it seems pov carves a hole out of one of them where it 
finds the other. I was getting some horiffic errors from the flying lava 
until I differenced it with the smoke's media container. The errors looked 
like shadows through the media but bright white. Anyway my experience is 
media "just does that sometimes" and you need to help it understand where 
the division is between your surfaces by using differences and such, I was 
just hoping someone understood the technical aspect of this better than me. 
i.e. I can work round it, but I'd like to know why I have to :)
