100Mbit are 12.5MByte so you are only getting 1/3 of the theoretical
throughput.

What's normal?

When copying a lot of small files the tranfer-rates are really bad. But
you are talking about video and audio, so that should not be the problem.

It also depends on how you do the copying. Are you using NFS? SMB? FTP?
SCP? Different protocols, different overhead, different speed.

And then it makes a difference if you are using a GUI or not. It is a
while back, but I compared some copy-speeds on one PC, and I'd quess
that the effect is also present when copying over the network. (Maybe
not as big):
