So why didn't they just rip discs with the vid data in the right layer, with ixtreme reading from this area?
Well it began in 2006 with old xtreme fw reading L1 from L0 due to technical difficulties making proper images and having the FW read it properly. Eventually that difficulty was overcome, but the xtreme FW of the day still expected L1 to be in L0 so ripping methods remained the same.
When ixtreme came out in 2007 alot of people expected this to change and L1 data to be read from L1, but this would cause everyone's xtreme (non splitvid rips) to not work.
I think c4eva and the team decided to continue to search for L1 data on L0 to stay compatible with the old rips. It was a compromise for compatibilty with the assumption that there was no technical way for MS to detect the difference.
Everyone was told that the FW would hide that the L1 data is being read from L0, and that MS would not be able to tell the difference - obviously that is no longer true.
(many people screamed about proper 1:1 support back then, saying it was the only safe way to do it, but alas it didn't happen)
So back in 2007, people started adding L1 data to the proper L1 spot, but they needed to also put it in the L0 spot to stay compatible with ixtreme. The belief was that if a new fw came out that needed the L1 data in the proper L1 spot, the disks will still be compatible. Problem is, the disks were still not 1:1, it had L1 in two spots, making total disc size too big. This is the current practiced splitvid method, L1 in two spots.
Still, we were told that the FW would ignore the extra video data on L1, meaning the extra data would be ignored and everything still appear legit to MS. Opinions divided on that issue, some insisting on making these types of splitvid rips, others sticking with the old non-splitvid method (most didn't know the diff).
Since neither were really 1:1, neither opinions were wrong, noone could say which was best.
We will have to see if the current splitvid method will be compatible and "safe" with the ixtreme LT. It is quite possible that we need to change the splitvid method to a 1:1 format. Or perhaps the new LT firmware will effectively hide the extra video partition. We need to wait to hear more from the team.
I know it's hard to follow, hopefully some of you can make sense of my brief splitvid history lesson.
