It's a huge amount of data since it's streaming ~900Kb/s (or 
thereabouts). I don't think it's really practical to look through all 
that to try to figure out exactly when the problem occurs.

Anyone know of any programs which can highlight 'anomalous' tcp traffic 
in tcpdumps?

Still, I'd be happy to try a capture and upload it somewhere if anyone 
cares too have a look at it. It'll have to wait for the weekend, though.
