So se have installed IIS Media services 2.0 (because se couldn't find the 4.1) versión on Windows server 2012 R2
We moved our Encoded .ism videos from our old Windows 2008 server and everything looks good, the player is loading and we can start playing the vídeo. But shortly after the audio and vídeo stop playing correctly:
Either the audio or the vídeo loop back in the middle of the playback.
Waiting before starting the vídeo seems yo work, like if the vídeo loops back because it hasn't finished loading.
IIS media service has been updated since 2009 so there would probably be some compatibility issue with 2012 R2. So it is recommended to replace modern media framework.
