some blu-ray discs cause bsod, others work fine

[tgentry1084]

hey, i am having playback issues with certain blu-ray discs on my computer. my computer specs are:

8 gb ddr2 pc6400 ram
intel core 2 duo 3.16 ghz e8500 cpu
850w psu
xfx geforce 8800 gtx video card v 6.14.11.7824
evga nforce 780i sli mobo
500 gb & 80 gb seagate internal hard drives
1 tb western digital external hdd
lg GH20LS10 optical drive
lg ggc-h20l bddvdrw optical drive v 1.03
vizio vx32l hdtv w/ dvi-hdmi connection (non hdcp, but i have software that resolves this issue)

i have over 30 hd-dvds and i have about 25 blu-ray discs. i use arcsoft totalmedia theatre (v 2.1.6.126) for high def playback on my computer. however, some blu-ray discs crash my computer. some movies will start playback before immediately crashing. some movies will crash in the menu. some movies play for up to 15 minutes before crashing. no movie crashes in the same place twice, and no movies crash at the same time as another movie. i have received one of two blue screen stop error codes from MS, either 0x0000008E or 0x000000EA. the six (6) movies that cause the bsod are:

die hard with a vengeance
indiana jones and the kingdom of the crystal skull
the incredible hulk
iron man
3:10 to yuma
forgetting sarah marshall

i believe i have listed all the information i can provide, aside from all the high def media that successfully plays on my pc. i can name those movies if need be. i have examined the studios releasing the bds that cause system failure, and there are no anomalies. if a movie by a specific studio crashes, there will be another release from the same studio that plays flawlessly.

i don't know whether this is a hardware issue or a software issue; the most confusing point for me is that some play and some do not. i have searched far and wide for solutions. i have emailed arcsoft. i have called lg. i have searched forums. i have never seen any information regarding problems similar to that which i have faced. i would be very glad to discuss any possible solutions.
