In the high definition horse race, it's HD DVD by a nose

Blu-Ray and HD DVD have been locked in battle for supremacy in the next-generation optical disc wars, but it has so far been difficult to compare the merits of both technologies in head-to-head tests. Both had rocky product launches, and when the first players were finally released, each had problems. Toshiba's HD DVD was crippled by long load times (now improved), while the Samsung Blu-Ray player was also no speed demon, and had some scaling issues to boot.
An unusual issue appeared right away. Training Day had cropping problems, with the Blu-ray version of the movie showing an estimated three to four percent less detail at the edges of the picture. The problem also "cropped up" in the other two films. With only one Blu-ray player available, it is impossible to say whether the problem is caused by the transfer process or by the player itself.
But Blu-ray's problems didn't end there. Occasional compression artifacts and brightness issues also led the site to crown HD DVD the winner. "In our first head-to-head comparison, we found the HD DVD to be superior," wrote Peter Bracke. "The unfortunate cropping of the Blu-ray image, coupled with more noticeable compression artifacts and an overall darker cast, can't compete with the more consistently pleasing presentation of the HD DVD."
