OK, so I'm a big Doctor Who fan. I set the DVR to record the DW Christmas Special as a "keep until I delete" to ensure it does not get deleted when recording additional DW's. The next day I go to watch the show and 34 minutes into the show I grab the remote to increase the volume. I accidentally hit the channel key, which stops the play of the recording and turns a live channel on. I've done this before, and no big deal, go back to the list and resume the show I was watching. Only this time I go back to by list and the DW Christmas Special is gone. I found the HR-24 recording history and the DW Christmas Special on the history. It is listed as "deleted to make more room for more recordings." What...it was marked by me as keep until I delete and I was in the middle of watching it when it deleted itself without the usual warnings. Has anyone experienced anything like this? Fortunately they will repeat the show on the weekend, but there are times I record something I want to keep indefinitely that does not repeat. I don't want this to happen again.
