When wowza encrpyts content using Verimatrix DRM, requests for pulling keys always specify DTV as content type.
If content is VoD then, requests are formatted as:
.. Query: r=20&t=DTV&p=0
It should be t=VOD for VoD content and DTV if the content is live.
Are you aware of this problem? Is there a workaround for this?
