Post command editing

[greedylobster]

Hi everyone, I am new to this, but I think this is a great tool. I have a technical question which willbe nosweat to answer I believe. When editing a DVD - I notice that, say if I am editing a menu - a post command refers me to VMG PGC3 (or any other PGC number for that matter). When I go the that PGC in the PostCommand it send me to, say VTS2 Title1 or VTS2 PGC3 (or any othe pGC number for that matter). In other words I get somewhere via VMG-PGC. My question is - is this the way the algorythm inside DVD has to work? Or whether it is possible/achevable to remove the extra step and direct the action straight to the target, bypassing VMG-PGC reference. It does not matter what DVD in particular this is as I have noticed that it is done routinely. I hope this question is not gooing to make someone have their eyes crossed... LOL I am just trying to uinderstand the logic inside of DVD and what's allowed/possible and what's not. Also I would greatly appreciaate if some one could point me to a couple of good sources to read about the syntaxis and the command language iinside DVD's. Not very technical, though if possible. Thanx-in-advance!...[/img]

You can bypass anything you want. What you see is the direct dvd-routing, what a dvd-author see is his GUI In other words, a dvd-author couldn't care wheter or not it routes over the VMG. As long as it's a static route you can simulate, you can change post-commands to match the pre/cell/post commands of the pgc that's being routed to. When I say static, I mean, a single route. When it's a single step you want to skip, it's always a single route. When you want to skip multiple steps, there might be multiple routes possible, and you really need to be sure that your edit will not ruin dvd routing. Take a look at: http://www.cdr-zone.com/forum/viewtopic.php?t=469 and then Tracing DVD Navigation. should give you a good idea on how to bypass unwanted content. Some people will say, why the hell would you want to do that, and not just auto-bypass it. Well, every inter VMG/VTS/VTS change will cause a routing delay on your stand-alone. This way the disc will respond faster. If you have a Disney dvd, which generally has about 15 VMG/VTS/VTS changes before hitting the menu, it will save you about 10 seconds in boot-up time compared to auto-bypass.

Hey, thank you Mirx! Very quick reply. I, to be honest thought it should be OK to do that, but just needed some reassurance. I find this application quite fascinating. It allows you to do so-o much and you, to a point, in a completel control of what you are doing. Thanks again!
