It's NOT DRM and we should back it
I can't believe The Register hasn't picked up on this. The proposed 'DRM' is entirely harmless and here's why. Scrambling the EPG does NOT prevent the video itself being recorded, it will still be broadcast FTA unencrypted and indeed there are other alternative sources of guide data. The BBC isn't stupid, it _knows_ this and the only conclusion is that they are trying to appease rights holders with a slight of hand. Now I hesitate to bring this up in a public forum where it might undermine what the BBC are trying to achieve, but this backlash against risks the same thing.
The developers of MythTV, myself included, are entirely unconcerned by this move because technically it's so laughable and therefore so obviously not what it appears to be. The BBC tech guys are as smart as they come, we deal with them on regular basis, and they are engineering the Emperors Clothes of DRM - a solution which appeases everyone. It's really quite beautiful and we should be lending them our complete support.
