I was= unaware of DLNA and read it as: DTLA. However, if you look at the "Overvie= w and Vision White Paper," you will see that DTCP/IP (administered by DTLA)= is required for the link layer of DLNA: http://www.dlna.org/about_us/roadmap/DLNA_Whitepaper.pdf - page 4, Table 1 The Wikipedia page lists some software that may or may not work: http://en.wikipedia.org/wiki/Digital_Living_Network_Alliance >=20 > The server does not support Digital Transmission Content > Protection: > http://www.dtcp.com/ > "Overview" presentation: > http://www.dtcp.com/documents/dtcp/DTCP_Overview.pdf >=20 > In essence, you are supposed to encrypt the video stream > lest you copy it. >=20 > I am a little surprised the TV would refuse to work with an > unencrypted stream, which is why I did not respond to your > first post. >=20 > Regards, >=20 > James Phillips >=20 > Hi James >=20 > I said the TV was DLNA compliant, those links at the brief > look I had appears to be the sort of encryption you would > see on a HD signal via HDMI that would prevent you say > recording HD content to your PVR device and then playing it > back to a blu-ray recorder and "recording" it to disc. I had I get the impression that DTCP is an "umbrella" DRM standard that that allo= ws the other DRM standards to inter-operate. DTCP is administered by the Di= gital Transmission Licensing Administrator: a consortium of five companies = including Hitachi, Intel, Panasonic, Sony, and Toshiba. HDMI uses another scheme called High-bandwidth Digital Content Protection (= HDCP) for encrypting the video. http://www.digital-cp.com/ http://en.wikipedia.org/wiki/High-bandwidth_Digital_Content_Protection DTCP will likely intervene in the step where you move the video from the PV= R to the Blu-ray recorder. When it comes time to record the information on the disk, a third scheme co= mes into play: Advanced Access Content System (AACS) http://www.aacsla.com/home http://en.wikipedia.org/wiki/Advanced_Access_Content_System The Wikipedia page appears to be more readable. > done a fair bit of googling on this before posting to the > list, it seems Sonys' implementation of DLNA is a bit > "loose" shall we say, I have seen a lot of people having > issues with DLNA complaint NAS devices not working with Sony > TV`s.

I would expect wmp12 to work because Windows Vista and 7 implement DTCP, an= d Microsoft is listed as one of the sponsors of DLNA.
