I think he means same resolution values in terms of PQ. Artifacting and other quality problems are another matter, but are steadily improving. I remember the first time I saw DVD rez DivX files. For the most part they looked good, but they still had problems with handling subtler textures like smoke and clouds. The codecs have gotten better since then, though and the WM9 hi def versions of T2 and Standing in the Shadows of Motown must be seen to be believed.

For the record, jimbo is correct when he states that both systems will be using blue lasers. Why blue? Narrower bandwidth, smaller pits, therefore more storage space. Hence the claims of 30GB for HD-DVD and 50GB for Blu-Ray. While an MPEG-4 HD system using red lasers was proposed and is in the manufacturing stage, this was not the format officially adopted by the DVD Forum and is currently only being developed in China for that market.
