DVRs Strengthen Relationships

In the myriad of news feeds and articles that I go through, I came across one about how DVRs help strengthen relationships. The article is here. It's very short and mostly covers its desirability in the home more than it does actually covering why or how it strengthens relationships, but the title itself made me think for a minute.
Although it hints at specifically referring to marriage relationships, it never actually states that. Of all the things that do strengthen our relationships with each other, the DVR (we have a TiVo, of course) wasn't one that I had ever thought of. We all have programs that we like and with different schedules it would be difficult to sit down and watch the same thing together were it not for DVRs. For example, I have watched the Tonight Show's segment on Headlines pretty much since the first time they had it. Often, Stephanie is asleep when it comes on. So, we can TiVo it and watch it together later and laugh and talk about it. Another one is the recent RNC. We were able to sit down together and discuss the things that were said instead of having only one of us here and the other not knowing what was said. There are many other things that we watch as well, but the point I'm making is that being able to record something and then watch it together allows you to: 1. spend time with others, 2. learn what others like to watch, and 3. have more common things to talk about...amongst other reasons as well, I'm sure.
Granted, there are alternative ways to this as well, such as watching programs and clips online together where it does not involve a DVR, but that's that the point here.
