You're right, DRM can't do anything from recording an analog output; this is why the majority of HD capable video players do not support analog output at HD resolutions and the content industry wants to use HDCP which will automatically prevent any system from outputting an HD data stream unless the receiver is authenticated. They haven't fully implemented this yet, but it's a deliberate attempt to close the analog hole.
In the meantime, most consumer HD video players can only output HD video through the HDMI interface that supports the HDCP protection, they don't give full output over any of the conventional analog output options.
