Don't believe them... I've had a tivo s3 in the Beaumont, TX area since September of 06 and have 2 S cards but they've never done things correctly. Card 1 works but is not authorized so doesn't get any digital or encrypted channels... Card 2 works properly on all (shows a subscribed on the auth where #1 doesn't even show the auth line). They've given me the runaround since then - from we don't carry cablecards to we don't support tivo to there's a new type of card out and only that one will work (obviously not true since my 2nd card works) to let us take your tivo and get it working - but wouldn't guarantee to fix it if they broke it. I've been working on getting them to fix it lately (I bought my Dad a Tivo HD and he's having similar problems so I figured it was time to start complaining again) and have had 2 truck rolls - but both techs take one look and say we can't get those to work (the first giving me the story about a new cable card). I handed the 2nd guy printout from this forum (thanks guys!) explained to him the difference between S and M cards and he was impressed - not enough to actually do anything but he took them with him. The local manager called me last week and promised to send out a tech who knew how to deal with cablecards today - but guess what no tech and no return call. A call to him today went directly to voice mail. I've tried to get them to just let me do the cablecard part but no luck. Looks like it's time to call the corporate office (hmmm now where is that number??) and then a complaint to the FCC.
