PioneerPDP508xd problem

[admin_exported]

I have the above plasma TV which is paired with a Sony DVD DVP NS3000, Panasonic DMP-BD55 Blu Ray,Yamaha Subwoofer YST SW325 and a Sky Box. Just recently the TV switches off after about seven minutes when playing a Blu-Ray disc with a Message on the screen SD05

"Internal protection circuit turns the system off

Is there a short in speaker cable?"

I have checked all the cables and they seem fine and correct, I'm assuming that as this problem only occurs when playing Blu-Ray discs the fault is possibly the player rather than the TV or speaker cables. Any suggestions please.

Now it seems to only happen with particular discs, the disc causing problems is a live concert Rush Snakes & Arrows, however when I play disneys Wall-E its plays just fine, does anyone else out there have problems with certain Blu-Ray discs?
