Maybe my two points are connected, but whatever :)
Firstly, £90? I have recently built a new media center PC and the BR drive cos £30, with bundled PowerDVD.
However, that particular version of PowerDVD was intentionally crippled (2 channel audio), and the latest version is actually 10, so even this Samsung drive has an old version, most probably tied to the drive as well.
Cyberlink do provide a trial, so you can see if the latest version does what you want on your hardware, but there are about 4 or 5 versions, all with varying degrees of crippledness. The 'best' version is £80! At these prices, most might as well just buy a standalone...
(With the digital nature of BR, I do not understand why the software is £80 and why it needs so much bloat. Simply render the 1080p image 1:1 on my screen, send the audio bitstream to the amp, job done.)
