You need to open up regedit and browse to:
HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Services > AFD > Parameters
You need to create TWO DWORD values "DefaultReceiveWindow" and "DefaultSendWindow"
You then set both these values using DECIMAL (not Hex) using this formula:
DefaultReceiveWindow = (Download Capacity in Kilobits * 1024) / 8
DefaultSendWindow = (Upload Capacity in Kilobits * 1024) / 8
For example, for a 10Mbit (10000Kbit) upload and download:
DefaultReceiveWindow = (10000 * 1024) / 8 = 1280000
DefaultSendWindow = (10000 * 1024) / 8 = 1280000

Once you make the registry change above, you'll need to reboot.
I didn't think it would do anything, but it does. I can now stream at around 15 Mbps, which is still not full speed, but adequate for streaming video purposes.
