Yesterday I reported in the "HR20: 0x13e - Discussion / Issues" thread that my HR20 recorded a show from one of my SD locals (KPBS 15, Sesame Street), but playback resulted in a black screen. An RBR still left me with a black screen on that recording. Since it was unwatchable, I deleted the recording from the playlist. The same thing happened today, same time, same show, same channel. Tuning to that channel is fine. I have an HR10 also set to record that show and it did so. I did delete the series link and replaced it today. This never happened under any other release. Any thoughts?
