Actually now that I think of it it wasn't any kind of general mpeg2 
knowledge but encoder documentation and behaviour. For tmpgenc and cce to 
be exact. They both had 15 as the highest you could select (for PAL 
anyway) and those two being the most popular encoders I assumed this was 
the limit. I'm guessing they made it so to prevent people from encoding 
streams incompatible with DVD.

Interesting how all the docs I can dig up say there are "restrictions on 
the GOP structure" but don't bother mentioning what exactly these 
restrictions are.

We're way off topic here :)
