The cablecard mess may be out of Tivo's control, but they could be using this time to make their DVR the best DVR that it can be. Unfortunately, they aren't. We've had almost 2 years with no progress on the HDUI, no progress on the second core. Amazon prime support still isn't there. There are some SDUI features that aren't available in HDUI yet. The platform remains somewhat unstable with low quality internet. Neither of my Premieres can reliably boot if the bluetooth remote dongle is installed. Streaming was there for a couple weeks and then disappeared. My iPad remote can't reliably detect that my Premieres are Premieres.
If Tivo could spare some developer cycles to fix the above, then maybe people would be willing to put a bit of extra effort into dealing with cable headaches if the DVR was truly superior.
