Yesterday, on the HR20, my Wife was watching Live Desk on Fox News. about 25 minutes in, they aired a story she wanted me and our sons to see, so she hit record (29 minutes into the buffer). When we got home, the recording appeared to be the full 2 hours, but it would not rewind past the part where she hit record (29 minutes). If I selected play from beginning, it still only played from the 29 minute mark. She wasn't using double play at the time, but this has literally never happened before. Believe me, I've been with the HR20 since the beginning (well, a month after the beginning, but who's counting) and I've had EVERY problem, but never this one. To clarify, I have had partially unplayable recordings, but in this case, it won't play what was in the buffer before the record button was hit, even though the progress bar indicates that the recording is there. This is what leads me to believe that it is a DLB related issue, but I don't know if it is a DLB issue or not. The live showing was fine, only the playback is affected. Well, only the playback before the record button was pressed was affected. I have not yet tried to re-create the bug.
