Yup all my hd channels are unwatchable with serious pixlation and sound cutting in and out. Started last Wednesday being just minor and now we cant watch hd channels. We have 2 cable boxes... DCX3510-M and a DCX3400-M and the problem is on both units. Sd chanels are functional and pic and sound are ok. Tried reboots but problem still there. Tested internet and my speeds are ok.
Please help we miss our HD.
