My install wasn't completely smooth, but it wasn't too bad. My wife encountered the first issue when she called the customer service line to make an appointment, but they told her RCN no longer offered cablecards. So, she called the local salesperson (who originally signed us up), and he arranged the install. The next issue came when the installer arrived. He'd never done a cablecard install. He expected to put the cards in and it would just work, but we saw "no channels available" and he had no idea what to do. He had never heard of pairing or initalizing, but both cards started working while he called the office asking if they'd ever heard of that stuff. Apparently RCN doesn't do pairing. All the channels appear to come in (based on the RCN website), and I haven't found any audio issues. Now my third issue (and hopefully the last) is that Tivo's line-up is screwy. It did the "is this channel x?" thing, and apparently picked "digital rebuild" which should be ok since according to RCN, that's what I have. Tivo's version of "digital rebuild" doesn't match, however, so Tivo suggested I use plain "digital" instead. It seems to be slightly better, but I switched, went through the line-up today, and found 8 incorrect channels (some wrong, some missing, some without guide info). I reported them via the Tivo website, so I'll see how long that takes. I think there are other errors in the MiVision package, but I didn't report them since I don't have the package. I'm in the Lehigh Valley, btw.
