I'm sure you know all this, but:
Any chance of changing your network topology so the path from the
Myth machine to NFS storage is not interfering with the "transfers"
You could even put a second NIC in the NFS box and create a second
network just for the Myth system I suppose, if one of the boxes
involved in the transfers was the NFS server.
There are 2 ways to get more bandwidth, add more in some way or
remove some of what exists from the overloaded path.
Just a thought.
