Use a 1Gbps ethernet connection, works for me :-)

Basically yes. The other potential option is to extend the x11rdp server
to handle the Video Acceleration API extension then extend libva to
divert the video through the MS-RDPEV protocol, thereby removing the
need for putting specific new support into the media players.

The only thing I am not sure about is whether the VA API can handle
being handed the full MPEG2/H.264 etc video stream. You might need to
take the broken up video stream and reassemble it before it can be
pushed through the MS-RDPEV extension.
