Launched a Server OS VDA session and opened Windows Media Player to play a .MTS format video.
Windows Media redirection failed and resulted in a "Windows media player cannot play the file." error.
The issue was not observed over RDP or in the hypervisor console for the server.
With the Citrix Windows Media redirection policy disabled, the video played fine on the server.
The issue was observed with XenApp 7.6.0, 7.6.200 & 7.6.300.
Apply a codec pack that supports the AVCHD format and .MTS containers.
VDA does not have the required video codec support for AVCHD format and .MTS containers.
