All the packets are 'small' (100-300 bytes) so doesn't look like this
is the problem.

I am slightly puzzled by something though... the two switches handling
layer 3 for these environments are each forwarding streams in
different directions (so far so good), but on one switch all the (S,G)
entries drop into flags 'T' (SPT joined), but on the other one they
stay in 'FT' (Register, SPT joined). But now it doesn't have the
'Registering' stuck permanently on the end.

What is the difference between being in 'F' mode and being
'Registering', and why isn't it taking the group out of register mode
as soon as it's got a RegAck?

Thanks,
Ras
