If daytime downloading works but wee small hours doesn't, in a reasonably
consistent manner, it does tend to point at something not keeping up with
the flatout rate the BBC can throw stuff at you in the wee small hours.
GiP is the only thing that any of this household uses that can fill the pipe
and hold it full for how ever long a download takes. We only have a tiny
pipe though, < 5 Mbps.
I don't think the streams use a link layer error correcting transport
protocol, so if a packet gets broken/dropped in transit it's gone forever.
"Transit" includes any (hardware) buffers in the NIC... Makes sure you have
the latest drivers for your NIC, see if there are any tweaks regarding
buffers in the driver.
Is it an "on board" NIC or a seperate card, on board stuff is normally "what
they can get away with" but all the same 70 Mbps sustained shouldn't be a
problem. One assumes you are saving the stream to the machines HD not a NAS
over the same ethernet connection?
