Saying DTCP is just a stream is also misleading. It is an entire system from stream to storage and playback. Only when the entire content path is secured, will you be certified to use DTCP.
DTCP-IP is not an entire system from stream to storage to playback. It is a transport only
DRM scheme. For storage or playback, the DRM must be handed off to another DRM scheme. PlayReady is one of the DTCP-IP approved DRMs for both storage and playback: http://www.dtcp.com/approvedtechnologies.aspx

Hey - I agree there. That is the key. Microsoft has its own agenda, which is why it is good to have a broadly industry supported alternative.
DTCP-IP is NOT
an alternative to PlayReady if you want to record.
