We had two back-to-back shows recording. We started watching show #1 from the beginning at about 40 minutes into live TV. At roughly 40 minutes into the show, that is where liveTV was when began watching, the picture and audio quickly became garbled and then seemed to start over from the beginning of the show. That was strange, but we didn't think too much of it. The strange part was that essentially the same thing happened in show #2--40 minutes in, it went all to hell. Fortunately, I deleted the two and was able to record from a later replay. But it was concerning. This was on a 622 connected via composite to a Dish-brand HD. Any thoughts?
