do you have full duplex? Then you have simultanuously 100 Mbit/s in both
directions.

IIRC one Voyager episode (~45min) takes ~1.2 GB = 9830 Mb
so we have approx. (9830/45)/60 = 3.46 Mbps

so even a 100 Mbps connection would suffice for 100/3.46 = 28.9
simultaneous streams in one direction.
(ok there is always an overhead of all the protocols there, but this
should be definitely enough for 4 streams.)

On the other hand, if he has only a 10Mbit ethernet, so two connections is
a maximum (3 * 3.46 Mbps > 10 Mbps)

@Axel: if you have a 100Mb network, you definitely should tune the
settings.
