Because I use a cable box, the Tivo records a tiny bit of the previous channel before the cable box can change channels to the new show. Normally this is just fine, but more than once in the last few years, I have scheduled a movie to be recorded and the tivo stays on the movie channel until a new program is to be recorded. If the new program is a late night recording, the new show will include a tiny bit of whatever movie is running on the movie channel at the time the new show starts. As the nature of the currently showing movie is unknown, once in a great while it will be adult situations that are being shown and this can get recorded at the front of the new program before the channel changes.
Example. I record Die Hard at 9PM on Showtime, on Friday Night, It runs to 11:30ish. The next show to record is DragonBallZ, one of my kids favorite shows. But Showtime is showing soft porn at midnight when the late showing of DragonBallZ starts (Other showings conflict with my programs, so my kids record the late showing) What happens is randomly the kids get one to two seconds of soft porn at the start of DragonBallZ.
What I'd like to see added is a "Safe Channel" option. So when the Tivo is done recording and no new program is scheduled immediately following, it switches to the safe channel. This assures that the content at the start of a recording will not be objectionable.
My wife would also love this feature as she would set Fox News as her safe channel on the Kitchen Tivo and so whenever she turns on the Tivo, there is a high likelihood that she has a full buffer of news to scan through.
This has been suggested many times before, but until Tivo implements it, try the following:
Set up some season passes for things that come on a lot of the time... ESPN's SportsCenter, for example. Look at recurring shows that come on CSPAN in the early-morning hours as well. Set these season passes to only keep one episode at a time, put them at the bottom of your priority list, and if you pick these shows well it should solve your problem the vast majority of the time.
It's all fun and games, until someone loses an eye.
