I have 3 recordings of Gold Rush that will not play. On the DVR, it shows 1.31 fps and I may get a single frozen frame. I checked all 3 of these. CPU is 30-50%. They do have commercials clipped. I've not had problems playing any other recordings on other channels. Playback is on AppleTV. I did manage to do a web playback, but it was challenged too, but would play with some interruptions.
What should I check to understand and fix this problem?
