Thanks for this response Kylie. I'll have to get in touch with the USA
Bookbinders and put the backward compatible notion to them.

Hi, Merv
HD DVD was one of the formats designed to replace normal DVDs eventually
lost to Blu-ray. and would most likely require an HD DVD player in less
the disc specifies that it is a backwards compatible disc, only released
uncertain HD DVDs.
You can find out more here on Wikipedia

Below is a quote from the relevant part from Wikipedia
<http://en.wikipedia.org/wiki/HD_DVD#Compatibility>
Compatibility <http://en.wikipedia.org/wiki/HD_DVD#Compatibility>
Backward compatibility is available with all HD DVD players, allowing
users to have a single player to play all types of HD DVD, DVD and CD.
There is also a hybrid HD DVD format which contains both DVD and HD DVD
versions of the same movie on a single disc, providing a smooth
transition for the studios in terms of publishing movies, and allowing
consumers with only DVD players to still use the discs. DVD replication
companies can continue using their current production equipment with
only minor alterations when changing over to the format of HD DVD
replication. Due to the structure of the single-lens optical head, both
red and blue laser diodes can be used in smaller, more compact HD DVD
players.
