Cyberlink's updated its BD Advisor (the HD advice having sadly, but understandably, falling by the wayside), to check for profile 1.1 (Picture-in-picture) and 2.0 (BD-Live) support. A quick download of the 4 MB app and a scan later, and you know if your hardware may need an upgrade to play movies at all, or to enjoy all the special features by checking out the new advanced tab in the new, slightly cleaner interface. Our request for a calculator to add up the cost of necessary upgrades has yet to be answered, though we're slightly comforted in the knowledge that the required equipment is a lot cheaper now than it was two years ago during our first scan.

While around here you're more likely to see a flame war erupt about Blu-ray versus HD DVD, on many computer gaming websites the war is over ATI and nVidia, with the two major video card manufacturers constantly leapfrogging each other in an attempt to benchmark the highest scores on games like Unreal Tournament and Doom. Ars Technica has a head-to-head comparison on how well the their latest offerings perform decoding high-definition content, using an Xbox 360 HD DVD add-on drive and some prerecorded 1080p and 1080i content. While both camps did similarly well, ATI was better at playing back VC-1-encoded HD DVD content, and nVidia held a slight edge on 1080i recordings. The benefits to both allow even older video hardware to take a load off the CPU, meaning home theater PC builders can pair a cheaper CPU and video card for playing back HD on the cheap.

Whether playing HD DVD and Blu-ray discs from a drive, or files obtained or stored via other means, you'll need plenty of horsepower to keep the HD flowing smoothly. Hardware Zone took a look at NVIDIA and ATI's competing platforms for hardware acceleration of h.264 and VC-1 decoding on PCs. They tested a few 1080i h.264-encoded movies from Japan and found neither solution was able reduce CPU load by more than 20-30% on their Core 2 Duo equipped test machine, with similar reductions on less CPU-intensive VC-1 discs. Overall they like the NVIDIA's PureVideo GeForce 7600 GT over the comparably priced ATI Radeon X1650 XT with Avivo, but check out the head to head for all the numbers before deciding which videocard goes in your next Media PC.
