U sing cable, sometimes I have an excel- lent picture, sometimes good, sometimes only fair. Comcast splits the signal to the computer and to the TV. I then split the TV signal several times. I've been told I need boosted splitters. Do I? There are four TVs in the house. I've also run a cable to the motor home with a TV. Do I need to upgrade my splitters, my cable, and/or add boosting splitters? The cable I'm using is 75 ohm, RG6/U. I also have empty branches wired for cable so I can move a set as I need to. Should I avoid that?

Help from readers
There was a terrific response to a recent request for reader advice on how to solve a camera battery problem. I need help again. Here's the e-mail:
Several years ago, we noticed that by the time we get to the end of a movie on DVD the audio and the video are out of synch. We have since replaced our old TV with a new LCD TV and we have replaced the DVD player and the cables. Nevertheless, toward the end of every movie we watch, we have the same experience. What could be going on?

At first I thought I knew the answer. Sometimes people use a home theater sound system but keep the sound from the TV. That can cause sync problems. But the sync problems would be constant, not just toward the end of a DVD.
There have been reports of sync problems with high-definition DVDs. But this reader's problem has occurred with two regular DVD players and two TVs. I realize access times from a DVD can vary based on where data is stored on the disc. But that doesn't commonly cause this sort of viewing problem. It's a mystery to me. I'd be glad to hear from readers with ideas.
