I have a two year old Roamio Series 5 attached to my antenna, no cable connection. I have recorded programs and watched while the program was being recorded. There were no pixilation or audio issues during the transmission, yet when I replay the program there are consistent pixilation and audio issues during the entire replay at random times. These problems have become more frequent during the last twelve months.

I would appreciate any thoughts about the possible cause and fix for these issues.

Thanks.
