Hey budsgirl,
Thank you for reaching out! I am sorry for the delay in response. The forums aren't monitored as closely as our other support channels. I haven't heard of any reports of CNN pixelating or getting audio drops. I would recommend trying the troubleshooting steps here. If you notice issues continue to persist, your best bet is to touch base with technical support to help fix the issue.
Cheers,

I'm having the exact same problem with CNN. Audio dropouts and pixelation. Only on CNN. And on both of my TV/PVR's. Have had this problem on and off for a year or so. Getting very frustrating !!
