Motorola 6416 DCTIII Shutting Off On Own

Sorry if this topic has been covered before. I've tried "searching" for an answer, but I didn't come up with anything.

We have the Motorola 6416 DCT III digital cable box/dvr through Cox Cable here in Omaha, Nebraska. Our box is consistently shutting itself off...at least once a day. Sometimes it will go off and on for about 1/2 hour. Everytime it shuts itself off I have to go through the settings menu to adjust for the "choppy" picture I get via 1080i output. We've had this box for about a year now and have never had these problems until about 2 months ago. Is it a matter of our cable provide constantly "upgrading" the service....or is it more than that?

Any help is appreciated.

Thanks Jim,

Well I decided to call Cox support and the tech told me that my box might have a bug which is causing it to turn off and on all the time. First though, he sent a signal to the box....causing it to load and refresh...hoping that would solve my problem. It didn't. Now I need to call Cox back and set up an in home appointment with one of their service techs.
