HR44-200 Play back motion artifacts, jitter, ragged edges - DirecTV

I am increasingly seeing motion artifacts, jittery pictures and ragged edges on REPLAY ONLY from my HR44-200. I emphasis replay because I called 800-Directv and was transferred to a "service center" that only wanted to sell me "protection insurance" and would not talk about the problem. My leased Genie DVR is not functioning properly and, since Directv won't help, I need to help troubleshooting it. I had called before and spoke to someone in India and was nice but told I needed examples of the playback. I now have the examples--program, date and time--and they only want to sell me a service policy. Any help would be appreciated.

This question, "HR44-200 Play back motion artifacts, jitter, ragged edges," is about DirecTV channels, programming, equipment, and sports.
