The version of CyberLink PowerDVD that ships with the WH08LS20 drive is an outdated release. The CD installs v7.3 and even after downloading the latest patch available from CyberLink I was still unable to play a recent Blu-ray title. As the patch is from 2008 it was obviously not designed for Windows 7, and it's possible there is an incompatibility with the OS or the fact that it is 64bit. Unfortunately CyberLink does not offer any discount to upgrade from a prior version; the online price is the same whether you're a previous or new user. I did download the trial version of PowerDVD v10 and verified it was able to play just fine.
