I had a quick search but couldn't find the answers.
My current setup is an Athlon 5000 X2 on an Asus M2R32MVP and a 2900Pro. Originally I was using a Sony Bravia KDL20S2030 plugged in via the HDMI socket (using a DVI - HDMI cable). All sound goes through an asus Xonar with an optical cable to a Ligitech Z5500. I decided to add a Blu ray drive so bought the LG GGC-H20L along with a copy of Powerdvd 8 ultra. The first blu I bought was Bram stokers dracula, which played fine, I wasn't astounded by the quality, but hey, it's a 10+ year old film. The next blu I tried to play was a recent one (can't remember exactly) which played the first few seconds, then stopped with a popup telling me I wasn't HDCP. Firstly i tried changing the cable, so bought an HDMI cable, and used the adaptor that came with the Graphics card, this had no affect. I then assumed that the Sony Bravia was the culprit, so I have just bought a Dell 2408. I have connected this with the HDMI cable again, but I am still getting the same message. I cannot think what else it could be, any suggestions please?
I have updated all drivers too, which has not helped.
