DVR recording issues

I haven't had the audio problems that you experienced but I would like to thank you for mentioning the recorded programs that will not play.  For me, this happens apx. 10% of the time.  Very frustrating.  The error message is "We have experienced a problem playing back this recording.  Please try again later."   One additional problem that you did not mention is that I am not able (sometimes) to record a program that I am watching.  I hit the Record button and it shows that the recording was successful but the show does not appear  in my Recorded Shows list.  It does appear in the Future Recordings list but the "Edit this recording" option is greyed out.  That is my warning that the show is not recording.  I have the Cisco 9865.
