Either route violates the DMCA, so such measures don't qualify as legal "solutions" to the DRM problem.
My understanding is that cable boxes continue to output everything over component, and the Hauppauge HD-PVR records it as H264 without any protection to a file. That could explain the thing you brought up if WMC users are the source of the pirated material you mentioned. The Hauppauge device would be a way to do it, and as I said, I don't believe Playready has been broken, so I don't believe the source is CableCard recordings made by WMC.
We were talking about WMC, Playready, and your notion that open source cannot ever implement protected content because the availability of the source code makes the DRM easily defeatable. I explained that's not true for programs like TrueCrypt, for having its source code doesn't help you crack its encryption. That's sort of the hallmark of a decent scheme, and I would guess it applies to Playready, which AFAIK, has not been broken. Now, if you have a live system, my understanding is that it may be possible to recover Truecrypt keys and later hack that one system. I have not heard anything like that is possible for Playready, which makes me wonder what exactly WMC does as the middleman between the CableCard tuner and the HDCP-equipped output device.
In summary, my impression is that being open source is not necessarily the issue, and it could be the expense of dealing with CableLabs that keeps software like XBMC from supporting CableCard. Whatever the case, if having the source code would open all the secrets as you believe, then it is likely someone would have figured out how to do it to WMC without the source code.
