NetPlay Video sources:

Any source that is already h.264, mpeg4, mpeg2, or mjpeg can be directly integrated WITHOUT needing to purchase a VTX100 for it.

Your media libraries on network share or NAS driver (DVD, Blu-ray, and music) can playback directly on each VRX via XBMC.  Once again saving you money, but also directly decoding the original Blu-ray files for the very best quality possible.

VTX100 is only needed for your live HDMI sources, such as cable/satellite boxes and Apple TVs.
