That seems to me a technical misnomer. Probably you mean:

Digital Restrictions Management(DRM)

Well you could sign a (your) Linux kernel binary, and have the bootloader
check that against some securely stored hash. And so on. However how are
you going to be sure someone isn't just VCR or MD taping the show, or
running the whole thing (including bootloader) in a captureing emulator?

Well, there is a device driver for the TPM from IBM:

Who knows? Maybe ask the mplayer developers.

Good (or bad) luck ...
