How CableCard DRM Benefits Microsoft

Vista has a big advantage in the PC DVR marketplace by being the only option for digital cable tuners. How can SageTV and BeyondTV compete?


I wonder how much Microsoft has actually fought with CableLabs about its DRM-scheme. Publicly, they appear to be butting heads but privately, Microsoft has a lot to gain by being the only option on the block. Could Microsoft be using the iTunes/iPod model of vendor lock-in?
