What I meant so say when I said better tech. was more storage capacity.
And:
Blu-ray format holds 25 gigabytesto 50 gigabytes of data with additional capacity possible to 200 gigabytes. HD-DVD holds 15 gigabytes to 30 gigabytes with a maximum of 60 gigabytes. The content partnerships favor Blu-ray, which has all of the major movie studios, except for Universal Pictures, backing it along with consumer electronics and computer companies LG Electronics, Panasonic, Samsung, Apple and Dell. HD-DVD has Universal Pictures in its corner along with Intel and Toshiba. A few industry players, such as Hewlett-Packard, Paramount and Warner Bros., have pledged support for both formats.
