We don't support WMV.
MediaSignage officially supports all of the Flash Media Formats which include:
Video Formats: Flash video FLV (H.263), MPEG-4 (H.264) ,MOV, M4A, MP4V, 3GP, 3G2, AAC (HE, LC), SWF
We HIGLY recommend you use FLV (Flash Video) with H.264 encoding as it supports
hardware acceleration and will run on the GPU (not CPU) and give the best performance
As for local playback, we support it through a local apache server that can serve files over
http://127.0.0.1 using our external video component.
