I agreen with Cloinjones. We pay for the damn hardware so what is the issue with having Linux HDCP or whetever decrytion is necessary to effect BD playback?.
Ok HDCP is a way of encrypting data as it goes between the computer and the display.
It runs over an HDMI interface. A display which is HDCP compliant will receive digital encrypted video over HDMI. It will also receive high-def (1080 i/p) OK via HDMI. Or at a push via VGA (latest Samsungs and LGs do anyway, Panasonic has crippled the latest Plasmas and LCDs to only go up to 768 lines so you can't do 1:1 mapping).
I don't believe there is any rule that says that if a computer puts out 1080 line video via HDMI that the display will reject it. AFAIK the way it works is that an HDCP/DRM-enabled computer
with DRMed OS and DRMed player software will reject any attempt to display more than 720 lines to a display that is not HDCP.
Summary- if your computer and OS and player are not
DRMed so are not going to use HDCP (cos you have to pay and sign a license with the red man with the pitchfork and never touch anything open source again), then your computer should be able to send anything it likes to the TV/display. "High-definition digital video sources must not transmit protected content to non-HDCP-compliant receivers" (says Wikipedia). So it is about the computer rejecting a non-HDCP display, not the other way around.
If you get a legal copy of some HD video that is unencrypted, you can display it in full glorious 1080i/p. Probably via HDMI. So there should be no technical reason LinuxMCE cannot display 1080 line content that you got onto your disk from an unencrypted Bla-Ray disc or however.
I am happy to be shot down in flames cos that is just my understanding of it.
No need for flames apparently Phoronix tested 1080p from a Linux computer to a Sharp LCD 1080 line TV (YMMV), over HDMI.http://www.phoronix.com/scan.php?page=article&item=942&num=1
Anyway you can always go VGA or DVI rather than HDMI. Not that much worse than the HDMI alternative, and in many cases this lets you do 1:1 mapping between graphics card pixels and display pixels and cut out the TVs stupid attempts at upscaling your nice crisp computer generated video by 5% (called overscan). 1:1 is often impossible using HDMI inputs but is possible with VGA/DVI. This will probably make more of a difference- getting 1:1 mapping right with DVD, rather than going Blah-Ray.
