Advertisements I'm sure there are a ton of threads and posts about this. I got a Series3 recently and the installation, surprisingly, went very smoothly. The first two cards the cable guy tried worked. Since then, however, it hasn't been all smooth sailing. The CableCard inexplicably loses channels randomly. The channel will just show a blank gray. Sometimes the channel comes back. Sometimes it doesn't. There doesn't seem to be any rhyme or reason to which channels go out, when and why. Also, once a day at least, all the channels go gray and I have to toggle between the cards to get the output back. It all feels very buggy and unstable. And while I haven't had a recording messed up yet because of this, I feel like it's only a matter of time. The cable guy is coming back to take a look but my appointment is over a week away. All in all, I'm not sure the benefits of Tivo (I'm a first time owner) is worth this CableCard instability and lack of peace of mind. My Time Warner (NYC) DVR - Scientific Atlanta Explorer 8300HD running Echo Passport - was much more stable and reliable. It's far from perfect but did pretty much everything reliably. Seriously considering returning the S3 and going back to the TWC DVR.
