PSC is one of Outlaw's cables -- it's a coax cable that can be used for coax digital audio, composite video, and (with three of them) component video.

When the display on the 950 blinks, is it blinking like off and then back on, or is it just displaying the incoming signal format on the right for a few seconds before going back to normal? If it's the former (display going dark), then I'd say your 950 has a problem. If it's the latter, then either the player, digital audio cable, or 950 is dropping the signal briefly (possibly very briefly) and the 950 is having to re-acquire it.
