Whats Split vid anyways ?
"If you put an Xbox 360 disc in a normal DVD video player you will see a screen that says, "To play this disc, put it in an Xbox 360 console." This happens because there's a DVD video partition on the disc which is split over both layers on original discs. On normal backups the video partition is all on layer 0, and hacked firmwares are supposed to redirect reads to the layer 1 video back to layer 0. However, it was discovered that some hacked firmware versions prior to the release of iXtreme were not doing this properly, and if the Xbox 360 host tried to read the entire video partition, the second part of it would be blank because the firmware started reading from layer 1 instead of continuing to read from layer 0 like it was supposed to. One solution to this problem was called SplitVid, and it works by appending the layer 1 video to the end of an iso (padded up to the proper position based on PFI) so that when these buggy firmwares start reading from layer 1 they will actually read the layer 1 video instead of blank data. The better solution is to simply upgrade your firmware to the latest iXtreme version because these old firmwares have even more security holes, even if you have a perfectly stealthed disc. iXtreme versions prior to v1.4 also have a bug in disc jitter (see 'Is there such a thing as a "bad kreon rip"?' for more on this). If you still want to add SplitVid (or even if you want to remove it) you can select your preference in the Misc tab. The default behavior is to not check for it and just leave it the way it is, because if you're using iXtreme firmware it doesn't matter if a backup has SplitVid or not; data past the game partition will not be readable by the Xbox 360 host."
