I have only had this problem with recorded shows from NGHD over the optical audio. You can skip back and it will play correctly the second time but eventually drop again. I think the DD audio is being overcompressed and the timecode is slipping. It is definitely the DD audio - I can turn to the analog out and it is fine.
It is quite annoying and I do hope E* is fixing this problem quickly.
