Bewildering Issue with BD playback

[robertvswild]

I've recently been stressed with a more and more common issue playing back store bought BD movies. The problem seems to occur at random from movies dating back a year ago to brand new on the shelf today. Some movies play and others will play to a certain point in the very beginning and then revert to a strange picture where everything looks like a melting oil painting. Eventually it cuts out and simply shows a green screen while still playing the sound just fine.

My set up:

Sony BDU-X10S Player
Intel Core2 Quad CPU Q9450 @ 2.66GHz
4.00 GB of DDR2 PC2 9600
Win Vista Ultimate 32-bit Service Pack 1
Two Sapphire ATI Radeon HD 3870 video cards in Crossfire set up
An LG Flatron W2252TQ monitor
Gigabyte EX38-DS4 motherboard


Sony tech support said they don't know what the problem is, they had me run their Cyberlink BD Advisor program and all green lights. I've tried updating firmware for the player but then my computer will no longer see the player for the next several reboots, so I'm not sure if the firmware update is taking hold or not. I'm using Cyberlink PowerDVD for playback and have all their updates as of tonight Nov. 11th 2008.

Any help would be greatly appreciated. Trying to take back a BD movie when it won't play is a hassle no one should have to deal with, and I seem to have to do so with 50% of the movies I buy due to this issue. Sony has washed their hands of it without giving me a solution, so I'm left out cold on what to do here.
