I don't have any answers yet, other than to say that pilot 
auto-detection was added fairly recently and prior to that some muxes 
were not locking at all in Europe. This may or may not be related.

I've bookmarked this bug, and I'll look into it over the next couple of 
weeks as I build a new tree.

The fact these have very high symbol ratas, is that the only thing these 
muxes have in common?

Regards,

Steve
