I apologize if this is answered somewhere else in the forum but I couldn't find anything. I have a new Tivo Roamio OTA VOX and it records programs from PBS channels just fine. However, several days ago, I programmed the box to record Survivor from our local CBS channel. I checked the To Do List beforehand and it was set and ready to go. This morning I went to My Shows and Survivor wasn't there and no message anywhere in the menus saying why it didn't record. So, my question is, are popular programs on the commercial broadcast channels being blocked by the commercial networks so they won't record on the Tivo? I know years ago certain programs were "copy guard protected" and wouldn't record on certain VCR's or DVD recorders. For instance, I have a Philips DVD recorder and it won't record any programs from the cable Syfy channel.
