I'm guessing I should put this here...
I have a blu-ray drive in me pc, cant remember what make or anything.
With it came Cyberlink PowerDVD 8 BD edition.
I have windows 7 installed, all should work fine.
However, the few times Cyberlink actually runs (most unstable piece of rubbish software i've ever come across), it claims not to recognise the disk format.
