Menu Buttons Ifoedit /Standalone/PowerDVD

[maa]

I've been experimenting with the logic commands and arguments and writing my own with IFOEDIT. I've come accross some strange phenomina.
Ifoedit will jump to the Root menu when I press the TITLE button but when I press ROOT it gives an illeagal command notice. This doesn't happen with PowerDVD. Also the TITLE button acts as a resume button when re-pressed so what does the RETURN button do? (nothing here anyway)
These inconsistancies force me to keep burning short DVDs to test on my standalone as this reacts in another way all together. Here the MENU button seems to follow the the same command as ifoedits TITLE button and the Title button acts like the Root button.

Any ideas?

Is there a software player we can trust ?
Or am I doing something totally wrong?

Hmmm...try reading this (http://www.mediachance.com/dvdlab/Help/connections.htm) on understanding a DVD remote's button functions.

Thanks 2cool - it doesn't realy answer the question as to what exactly Ifoedit calls though (and why it doesn't like it either)

As it says on that site - its a mess of Terms

The problem is just the names of the buttons. The DVD Forum sanctioned names are title for the VMG (video_ts.*) menu, and root for the highest level menu of a title (lives inside a language unit on a vts_xx_0.* file)
But some makers didn't like the names, and changed to TITLE and MENU or (Sony) DVD MENU. They then mixed up the meanings. Sony, for example, goes to the TITLE menu when you press DVD MENU, and goes to the title ROOT when you press TITLE.

When you say IfoEdit jumps to the root when you press TITLE, are you sure you mean root? IfoEdit uses the same names for the buttons as it does when interpretting the files. TITLE menu lets you choose a title, ROOT is the top level of a title.

Also the player makers are free to add features, Sony, again, remembers where the disc was when STOP is pressed, and can resume from there even after a power down. RETURN takes you back to where the movie was interrupted by a menu button, regardless of how many submenues you've looked at, while pressing the menu button again goes back one level. None of these features are required.

Best advice - figure out what the buttons mean on each player, then make sure the correct menus are shown. The owners of other players will figure out their buttons and use the right ones.

btw - I had to grab my remote and read it, I only know where the buttons are, not what they say. Who can read grey on black 6pt text in a dark room?

Ah - thanks for your reply mpucoder,
as I'm re-programing the basic menu commands of DVD Lab I've become entangled in this mess because DVD Lab only uses an empty title menu to start the DVD and the commands take you imediatly to the root menu in vts_01_0.ifo.
I was under the false assumption that the root is the same as in DOS being at the top of all directories.

So when I press TITLE it is of course taking me to the VMG and following the commands there which take me back to the root menu of say vts_02_0.ifo.
Silly me - I programmed it to do this but got confused on the way somewhere.

Now, when in vts2, I press the title button in ifoedit I get to the last menu - the one that induced vts2 - thats what I want. If I press it again it acts as a RESUME button. I'm just not sure at the moment why ifoedit's ROOT button gives me a illegal command when PDVD doesn't and the RETURN button does nothing.
