"As always seems to be the case with multimedia software, there are a number of versions on offer. This Ultra Edition is the most expensive and feature-rich, while the Deluxe Edition (£40) offers the same program but without Blu-ray or HD support, except for MPEG4. At the low-end there is the Standard Edition (£30) that lacks any form of HD support.
CyberLink PowerDVD 8 is as powerful and versatile as previous editions but in order to make the most of it you'll need to upgrade to this Ultra version. Blu-ray support is slick, as is the interface, and we found it worked well. If movies are a key component to your PC setup, you need this software. "
