Amazon has all their HD DVD titles at 50% off.
I know nothing of the two formats, but would it be possible for a firmware hack that allowed blu-ray to be played on HD DVD? Seems possible to me, but I know nothing of the two, and therefore its probably improbable. Would make this a good investment though
No, BR will never play HD-DVD disks. Similar formats hardware wise as in they both use blue lasers but different encoding.
