DRM Recordings Tied to PC or MAC?

post #1 of 4
Thread Starter 
Everyone notes that protected recordings under WMC are tied to the PC they are recorded on. But are they really tied to the PC or are they actually tied to the Ethernet MAC of the first network adapter? I know for most this is a distinction without a difference given the prevalence on on board Ethernet on motherboards these days. But if one could disable the on board Ethernet and use a PCIe based card instead, would the recordings be portable to that card?

It would be nice to be able to save recordings when upgrading an HTPC's system board by moving the card to the new unit with the drives if possible.

WMC recordings aren't just tied to the PC, they are tied to the Windows installation (though I'm not sure to what exaclty). You lose them, if you e.g. do a clean install. Sometimes even installing certain driver upgrades may cause DRM issues.

That's depressing. I assume a GUID is created at install time (using time + MAC) to be used as the DRM key then. Thanks for clearing that up for me.

More correctly, it's tied to a specific PlayReady component installation. If you reset PlayReady, you can lose the ability to play back your recorded content even though it's the same OS install.
