APHZOMBIE.. The article you quote makes 3 errors:
1. HDDTV will drive the migration on to new formats, or would you rather watch low def film releases on your gleaming new HDDTV ?
2. There is no penalty to migrating, your old dvd library will play on the new machine.
3. There is no penalty to buying a new machine. Chinese production will tumble the price within 2 years.
An interesting article on technology including HDDTV :)
Sadly, your assumption that the new formats can be authored on des is incorrect...its not difficult to understand, have posted details above or just refer to the relevant format specifications:)
