Which is Quicker in HDMV - changing pages, or enabling buttons?

[dvdboy]

I've done some experimenting before where by I update a separate BOG which contains additional information to the actual button.

Not easiest to explain, but imagine a list of buttons to access bonus features, and to the right of the list of buttons is a single BOG, which contains buttons that display a thumbnail or text for each bonus feature.

When you select down on the remote, the bonus item button auto-activates which updates the thumbnail bog to display the correct button, and then enables a second button in the initial bog that the user press enter on to access that bonus item.

There's a noticeable pause on the PS3 while the commands are executed, and I was wondering if anyone has had experience of this, and whether it would be better / execute fast if I just made each option a separate page in the IG so that when you navigate down from one button to the next it just executes a SetButtonPage.

I'm authoring in Scenarist.

Thanks

It's probably easier/safer to do it via multiple pages. The major problem you can encounter with this is buffer overflow if you have a lot of pages or a lot of thumbnails. You can optimize a lot all the graphics if you do 'the multiple-bog way' inside Photoshop with the Designer plugin, and then duplicate all the pages inside Scenarist, keeping only the needed buttons every time. This is because the background graphic inside each page is still the same (and counts for one). If you do multiple pages with Designer plugin, each page will have its own palette and thus the graphics will be bigger.
It is a time-consuming job but if you need to get the job done... you need some sort of sacrifice ;)

Thanks mp3dom,

I did a project recently where I used the 'duplicate the page in Scenarist' trick - it's certainly a good way to make savings across very similar pages, and hopefully it'll navigate on disc quicker as it's just a single command being executed, rather than several commands across a couple of buttons, and as you say the authoring will be simpler.
