[glarus1]

Hi there,
I'm new on this site, but I would like to share the problem I 've got in hand..!
I've just been in US, and bought a Sony B-R BMW-100A burner..brought it back to UK, went and bought the HDCP compliant graphics card "ATI Saphire-Radeon X1650 Pro"...Put them in my PC (HP-MULTIMEDIA, WINDOWS XP, ets...) I've checked with the guys from the shop to see if my pc can handle the burner and and card, and acording to the PC-WORLD Shop it's ok...Downloaded the softwear from Sony and recomended by them "CyberLink recently released PowerDVD BD"...Any how so far so good..I've followed their's instruction, regester the number from the cd-rom provided with the Burner...conected the pc to my Pioneer xde6436 via Monster DVI to HDMI cable...i put the T2 B-R DVD in...it starts to play it for 4-5 seconds, the an error mesage pops up sayng that HDCP IS ENABLE, BUT I can watch the movie on down resuluted via VGA cable...Any way,I now that few guys on this forum faced the same problem like me few months earlier, so any help will be appretiated...!
