Hi. I've just started burning DVD's and I'm having fairly good success. Splitting dual layers is still the hardest for me, thanks to mscogna for that excellent walk-through. Also thanks to drchips for that unbelievable handling of synth's problem creating his own IFOs. But what I'd really like is to understand the nuts and bolts of the IFO files. I can't find a detailed overview of what does what in an IFO file. Can anybody point me to some detailed, readable overview of the IFO file protocol?
