A Statistical Comparison of HD DVD & Blu-Ray Reviews
An anonymous reader writes "Gizmodo today posted a statistical comparison of over 300 HD DVD and Blu-ray reviews published at High-Def Digest since the start of the high-def format wars last Spring. Their findings? Overall video quality between the two formats is nearly identical, however Blu-ray titles were slightly, but definitely superior in audio playback, while HD DVD titles had far superior standard def features and moderately superior high-def features."
I guess you haven't seen the 720p or 1080p x264 (H.264/AVC - same codec that many of the HD-DVD/Blu-Ray movies are using) rips on private bittorrent trackers or Usenet. A standard two hour movie will fit on a DVD5 at 720p with 6 channel AC3 audio and a bitrate of 4.5-6 mbit/sec. While this wouldn't look great using xvid, H.264/AVC High profile can create great quality. x264 using Sharktooth's HQ-Slowest profile is very impressive. A 2 hour movie can fit on a DVD9 at 1080p at 7-8 mbit/sec, again with very good quality.
Hell, I've seen some 2 CD sized x264 rips from 1080p sources that blow DVD out of the water. Forget about the MPEG-4 ASP codecs like Xvid and Divx. Now that we have H.264/AVC, we can achieve excellent results at 720p and 1080p down to DVD5/9 sizes.
