I'm not real familiar with the Sony player problems jkenvin has pointed out (have more experience with Panasonic and Toshiba players -- I know plenty about all the grief surrounding Panasonic's A110/A310 players...), but one thing occurs to me. If the player in question is one of these problem Sonys, did you re-arrange anything in the equipment rack when you installed the 950? If the player is in an environment with a higher ambient temperature and there's a part that has a reputation for overheating, that extra heat could push it to the overheating point even though it didn't exhibit the behavior previously. It is possible that the overheating causes the player to malfunction briefly, resulting in the audio signal disappearing momentarily (or perhaps dipping too far for the 950 to keep its lock) and the 950 being forced to re-acquire the signal. It's just a thought -- maybe move the player to a more ventilated location and try to reproduce the problem?
