I recently upgraded to a Sharp 50" flatscreen HD TV. Everything worked great until I went to PAUSE the DVR and there was a very annoying BUZZING NOISE every time! It got to the point where whenever I was going to PAUSE, I would have to hit MUTE on the remote and THEN PAUSE. My brother found a fix on another discussion here and I wanted to let some of the members know that their FIX did WORK! But for some reason I was unable to post. So I wanted to let the Cox moderators know (because I noticed that they didn't have the answer, but another member did) that I was able to fix the problem by going to the CONTOUR SETTINGS, clicking on AUDIO/VIDEO, then AUDIO SETTINGS, then DIGITAL OUTPUT. Once I switched it to PCM (Pulse Code Modulated) instead of DOLBY DIGITAL (AC3) the buzzing IMMEDIATELY stopped. The downside is that I don't have Dolby Digital sound but since I don't have external speakers, I haven't really noticed a difference. The only difference is that there is NO MORE ANNOYING BUZZING!! Hope this helps others out there with this issue.
