No Dolby Headphone (and other functions) in PowerDVD 3.0 trial version?

[tonetgs]

Hi. I downloaded the PowerDVD 3.0 trial version from the Cyberlink web site to test my Pioneer 114 DVD-ROM drive, but a number of functions are grayed out, particularly the Dolby Headphone option which I'm most interested in trying out. Other major functions disabled include the Dolby Pro-Logic decoder and the Hardware Accelerator. I was under the impression that the trial version was exactly the same as the final version except for the audio and video time limits. Is this not the case? Are the aforementioned functions meant to be disabled?

Thanks in advance for any info.
