The White Dragon edit is very elusive. I did a lot of digging around a while back and found the only copies were sent to the recipients by the editor in physical form ie: actual discs. There was supposed to be an updated version made which was to polish some the effects and scenes created.
The editor has a youtube account and I tried to contact him/her many times without any joy.
If anyone does manage to get a copy please pm me as I would love to see thic cut.
