Streaming HD Video to Xbox 360

I've been experimenting with encoding HD videos using EncodeHD and then streaming them to an Xbox 360 via TwonkyVision from my QNAP TS-101. The QNAP TS-101 is a small NAS device with 64mb RAM so I think its a safe assumption that no transcoding is being done.

I first took a sample video from here and then encoded it using the various presets. The files were then copied to the QNAP, and then accessed from "Video Library" on the 360 (note: not via the Media Center Extender).
