Streaming to a Microsoft Mediaroom set-top-box/emulator

Dear All,

Im trying to stream the sample.mp4 file to a mediaroom set-top-box/emulator but no luck at all.

The error i get on emulator console is:

[AV.MediaTransportFailure]: Reason: ToDetuneNativeAVEngineDetuned, Additional Info: [empty]

The wowza url is: http://192.168.1.156:1935/vod/mp4:sample.mp4/Manifest

(of course it only work on my network)

And the manifest file is something like:
