Ahhh  That's the kicker.  Same problem here.  The problem is that there
is not enough dsp resources in the device to handle more rtp connections
that there are ports.  So I've got the DG-104S and it supports a max of
4 rtp streams.  I consider this issue to be a bug with the dlink
firmware because it does not fail gracefully.  The device gets left in
an unstable state if it runs out of dsp resources.
