Acer :: Blu-Ray Player

Got an Acer Aspire 8920, bought last august,I got it hooked up to a Sanyo hdtv via hdmi at the highest resolution, Ive played one blu ray before just to test it [ the incredible hulk] and it worked fine, but that was the only time i played blu ray..... yesterday was the first time i bought blu rays for it though [pitch black and chronicles of riddick] excited i put it in asked me for updates which i did and bam played it but when id go to full screen it would startlike flashing [like the screen goin on n off... you could still see the image but it with the flashin in between] n then it crashed so when ibooted it up again it wouldnt play it would just stay in a black screen

So reading around and people were talking about the area changing it from A to B so i did, and seemed to be reading the disc again, but the flashing kept happening...its like watching a video game goin at a lower framerate, it just keep flashin n jumping from scene to scene

so i kept reading and found that the acer arcade delux might be the problem so i read that powerdvd is the best player...went, bought it installed, not only crashes on me sometimes, but when it gets to play, again when i put it in full screen, gives me the same flashing tried at a lower resolution i get the same thing
