According to a recent study, owning a DVR can improve your relationship. That alone may be just the ticket to convincing your other half to give you the green light for that home theater PC you've been wanting to build. The study was commissioned by a company that makes digital pay TV equipment and looked at 1,000 DVR users from the U.S., U.K., Italy and Australia. Of the U.S. participants, 79 percent said DVR ownership has improved their relationship with 43 percent reporting they are happier in their current relationship because of the DVR recording and time shifting capabilities. While we're spouting statistics, 80 percent of those with a DVR said they couldn't live without it ranking the device just behind the washing machine and microwave in terms of importance.
