I don't think it's necessarily unethical to write such DRM software, and I'd be interested in hearing your argument as to why this is the case.
It's not as if the software causes harm; indeed it probably reduces the potential of economic harm to the content providers. Assuming it does exactly what it claims to do, i.e. decoding of video and audio content dependent on a provided decryption key - then what is the ethical problem with programming an algorithm for that?
