For beginners, I recommend hiding, with Auto Bypass on, b/c it’s easy. You don’t have to mess with the structure. Deleting things are meant for advanced users when they already know how the dvd structure and commands work, and how to fix it. If you don’t take a crash course and spend time reading, and even if we help you with this dvd, you’re going to have problem with the next dvd when you’re deleting things.
When you delete VTS, you have to delete the VMG Title as well, but then there will be other red things popping up. So it’s not going to end there. You also have to fix the menu navigation as well. The strategy is to delete one item at a time, then see where the red items pop up, look in there and try to fix it. The problem is you have to know where it will go first before deleting, so you know how to bypass it. e.g. you have A -> B -> C -> D, and you delete B & C, so you want A -> D. This means a trace ahead, making note of the state of registers, is required so you know what the destination is.
As I mentioned on the other thread, w/o the files, I can’t help you. But before that, please update to 3.4.2 from your account first, then we’ll go from there.
