Ive spent like 4hrs with this problem,i have same LG as U and gamin beast PC.Simple solution (dont want 2 bother U with whole action) is : b4 U start PowerDVD (my ver. is 9) unplug ur PC from internet,than when the movie will b runnin w/o any problem ,U can plug it back.
I have runnin AnyDVD with BD Live "on" (U have 2 turn it off on regular BD players),if U disable this option in AnyDVD,PowerDVD wont even start the movie propely.
Good luck 2 U and let me know if this help.
