Ok. Let me know if you want access to 13 TV channels with various
timings characteristics. That might help you find the bug.

Agreed, but I also stream to people with ADSL and with NAT.

The issue with ADSL is that some Telco has close-to-zero sized
buffer on the egress towards the customer and near stupid rigid 
bandwidth control. That poses a problem when you do

     server---normal-speed-net---high-speed-net---slow-last-mile

Data might arrive at the 'slow-last-mile' in small mini bursts
which by the egress router with the stupid rigid bandwidth control might 
get translated into smaller 'over the limit' streams. Just stupid 
design, but hey, a lot of it was designed by bellheads longing for the 
days of TDM networks still hoping this fling for packets switched 
networks will go over.

The issue with NAT you know.
