MS screwed over a ton a people with WMC. And when I say a ton, I mean a small vocal minority that require cablecards with Play Ready.
Well, that would be . . . me. But the real source of difficulty there is DRM and HDCP. Whether the software component is called "Play Ready" or "HD HomeRun DVR" -- that's something else. So far, I don't think we've seen it done better than in WMC. "HomeRun" is just an example of a proprietary solution for people with MS-orphaned SiliconDust hardware.
I have to come forward and admit something that "small vocal minority" doesn't adequately describe. A lot of us, and certainly before HDCP changed things, invested time, effort and a few bucks in DVR capability, experimenting with movie editing software, grabbing clips and putting them together. Eventually, we saw how we preferred the interface of WMC, which offers functions beyond any STB menu and channel guide.
We racked up experience in troubleshooting WMC malfunctions and nuanced configurations. Initially, it can be a confusing ordeal, but like anything, one becomes familiar with navigating through it. By this time, with everyone locked into the HDCP constraints, STB cable-TV subscribers were also acquiring TIVO and then cable-provider DVR or on-demand features.
But after all that DIY suffering, we don't like giving up what works really well once properly set up, and we don't want to dump our cable-card triple-tuners.
Maybe Windows 10 has potential to accommodate internet-TV subscriptions without using separate interfaces. But with a cable-subscription with really good premium-channel coverage, one is not eager to just switch over to a handful of different subscriptions and uncertain possibilities for integrated access, even if we would also lose what can be above $200 in a bundle of services including internet, Cable-TV and telephone.
But it is a continuation of the conflicts evident in the 1980s with Betamax and VHS -- whether you can "copy" broadcast captures, digital rights and the Jack Valenti media Nazis. A user may not have in mind to abuse copied content, but the restrictions imposed through HDCP completely changed the ball-game and added difficulty for everyone. Maybe the situation encouraged providers to offer DVR and On-Demand when they might not have done so otherwise. I'm not sure.
