I confess I wasn't even thinking of Windows.  I don't have either of 
those systems, but I'll guess that Windows 8 uses the same TCP 
auto-tuning mechanism as Windows 7.  The auto-tuning can supposedly 
scale the receive window up to 16MB, which is ample.  If auto-tuning is 
switched off, the system uses a receive window fixed at 64K, which seems 
likely to reduce throughput and cause more rtmpdump difficulties.  OTOH, 
maybe something about the auto-tuning is causing problems.

Basically, I'm clueless here. FWIW, here's a link I bookmarked for 
Windows 7 that explained the auto-tuning setting:
