By losing sync, are we talking about the signal dropping out and being re-acquired? If so, there are a few possibilities that I'd invetigate: the interconnect (is it loose or is there any damage like perhaps a pet chewing on it), the disc(s) involved, and heat buildup at the player and at the 950. It is possible that excessive heat buildup in the 950 could cause similar behavior. If you haven't done so already, I'd also run the question past Outlaw Tech Support .
