Has anyone had problems with their S-video input or output on their 950? I've been having some sporadic problem where the picture will go either completely black, or more often the picture will break into basic colors with just outlines of the images remaining. Both problems last only a few seconds before the picture returns to normal but they cycle fairly regularly every minute or so.

I've narrowed the problem down to either the cable or the 950's s-video input (no problems watching DVD through component input or satellite run directly to the TV). If anyone has any insight I would appreciate it before I go and tear apart the the rats nest behind the system. thanks.
