When I signed up for Comcast in my current house about eight years ago, it was no trouble to get a multi-stream CableCARD for a TiVo HD.<p>When it died a few weeks ago, I replaced it with another TiVo.  Same card worked fine for the non-premium channels that I get.  I discovered that I can even watch on-demand shows now after pairing the card over the phone.<p>I had no idea that set-top box rental fees are so high.  Makes the $600 I paid for a Roamio Pro with lifetime service seem quite reasonable.<p>One thing I&#x27;m annoyed about is that Comcast now encrypts even local broadcast channels, so the tuner in the television itself is useless.
