I was thinking instead of moddifying dvdrom firmware on the xbox drive can we not moddify the firmware on our burner to change the media type (bitsetting).

We know have the abilities to change the dvd-r/dvd+r to dvdrom so why not hack that firmware so that it will sign the dvd+r disk to whatever the bittsetting is on the xbox360s original disc.

I believe that pressed DVDs can (and do) have data on areas where burnable DVDs have no dye.  So no change to the burner firmware is ever going to allow writing to those areas of the media.

If I understand correctly, the X360 DVD security sector is in one of those non-burnable areas.  The talked about X360 DVD drive firmware hack essentially redirects requests to read data from those no-dye areas, to areas where dye is present on burnable media, combined with a special ISO maker (Qwix2?) that injects the read security sector contents into a writable area on the destination media.

Similar to the system which Sony used on the PSX/2, whereby special errors were pressed on the original disc which consumer burners either skipped or corrected, it probably wouldn't be technically impossible to manufacture working x360 discs if you had thousands of dollars worth of disc pressing equipment, but it can't be done with standard consumer user drives.

In theory you could do this with DVD Authoring disks and drives (~3.5 gig) but you will run into capacity issues, besides I think those drives and media are extinct by now.

What you want is a 1:1 physical copy of a x360 disc. Well, to my knowledge this isn't possible even if you were able to modify the firmware of a burner.

For the xbox 1, it's going to be at least hard to modify a burner to write backups that play on a unmodded xbox, but I think that in theory it is possible. You'll need to be able to:

1. Write to lead-out (the security sector)
2. Write RAW data (sector header of the security sector)

So, to do this, you'll need to do some VERY severe modding, both your drive and the burning software. It is a LOT easier to hack the FW of your xbox 1

For the 360, things are even more complicated. Since it does some timing, related to the bad sectors, you'll need to replicate these bad sectors and that is something I suspect that a consumer burner NEVER can do ...
