I've tried Googling this but I haven't found a decent answer... alot of "maybes" but no "yes's". Is it possible to have a triple layer DVD? Since dual layer is simply a second layer underneath the substrate accessed by a different focal point, isn't is feasible that a triple layer disc/drive be made available? Blu-Ray has done 4 layers officially with 8 layers on the table next. I don't know if that's a limitation of DVD's or if it's just never been thought about. Anyone?
