Let's try this dead format with a lot of potential...
A little bit of history:
HD DVD (short for High Definition/Density Digital Versatile/Video Disc) is a
discontinued high-density optical
disc format for storing data and playback of high-definition
video.Supported principally byToshiba,
HD DVD was envisioned to be the successor to the standard DVD format.
On 19 February 2008, after a protracted format
war with rival Blu-ray,
Toshiba abandoned the format, announcing it would no longer develop or
manufacture HD DVD players and drives. The HD DVD Promotion Group was dissolved
on March 28, 2008.
The HD DVD physical disc specifications (but not the codecs)
were still in use as the basis for the China
Blue High-definition Disc (CBHD) formerly called CH-DVD.
Because all variants except 3×
DVD and HD REC employed a blue
laser with a shorter wavelength, HD DVD stored about 3.2 times
as much data per layer as its predecessor (maximum capacity: 15 GB per
layer compared to 4.7 GB per layer).
