The eventual aim of DRM is not 'protecting copyright'. It's turning all forms of content into PPV.
Take a look at HDMI (the new all singing HDTV interface). Yes it looks all snappy and has the audio on the one cable. But HDMI is designed to work only with other 'approved' HDMI devices so that the data is always encrypted and DRM covered. You won't be able to capture the 'analog' hole, because there won't be one or you'll have to do some awesome reverse engineering to fool a HDMI video card into beleiving that your DVR-R, Software etc is actually a legit HDMI receiver.
The Web PPV scenario is poor form. I can sort of understand why they do it though. DRM is broken quicker than it it can be relied upon (hence Windows DRM11 now). If they let you keep the PPV with a long-term licence, eventually the crypt will be broken and it'll end up on the net. Thus 'hurting' DVD revenue.
Personally, I feel a little ripped off when I pay US$40 for a low-quality PPV (600kbps works out to about VHS resolution) that isn't as reliable as it could be (it was obvious that the encoder failed at several points during UFC66) and that I can't 'legally' record.
