I don’t think so. We see copy protections in CD, DVD and also HD DVD with AACS in addition to Blu-ray.
The computer industry for hi-def is quite overwhelming with Blu-ray products, ie burners, players, software, media. Also blu-ray is currently 3rd generation with its 6x burners. Blu-ray blank media is also supported by more CE industries.
In respect to software, the developers releases many kind of authoring software for blu-ray since the burners are pretty widely available.
Nevertheless, HD DVD blanks media are/were available though from Verbatim, Memorex, Ridata and some other CE. Just too bad that HD DVD group didn’t release their burners fast enough.
