It's looking more and more like the retail DVD for XBOX games is NON-COMPLIANT with the DVD FORUM, and OSTA UDF Compliance.
To use the Term DVD, a manufacturer need to maintain certain conditions for their released DISK. One of the conditions is to maintain OSTA (Optical Storage Technology Association) compliance. To do that, they must place data in a predictable predetermined manner on the disk, with proper descriptors for where to find volumes and partitions on the Disk.
MS, and Smart Storage, Inc may not be producing these disks in compliance with current ECMA-267 or 268 standards. It would appear that MS has moved descriptors, or has chosen not to place some of them in the predetermined locations (or has encrypted some of them). From what little I understand, that is a violation of the OSTA Guidlines for compliance, which in turn would violate the guidlines of the DVD specifcations.
To be OSTA complaint, all of the descriptor and pointers need to be compliant. This doesn't appear to be the case, at least not on the test DVD used. The Data volume we can view on the PC is clearly defines, and volume and logical block descriptors in place. Attempting to view the rest of the disc doesn't work. OSTA compliance requires that a disk to be compliant, must provide the descriptors necessary for the disk to be read on units that carry the DVD tag.
MS may well be using the TERM DVD on it's media improperly! XBOX disks only read partially on PCs.
I guess what I'm getting at is MS DVD's do'nt fit the spec, and as such SHOULD be called something else entirely. Would love to see MS backpedal on this one
Seem just like what happened in the last year with CD in the Music industry. They carry the CD name and logo, but are out of spec, and not fully complaince.. the result being some of those anti-piracy CD's wouldn't play in compliant CD players.
'nuff ranting... I tired myself out.
