play once media (when disk inserted)

Declan wrote on 7/14/2007, 3:10 PM

I am trying to author a DVD which will play one of the media clips once (a copyright notice). Once played, I don't want it to be accessed by either back/forward buttons or when the DVD is stopped and restarted. i.e., only when the disk is inserted.

I created a DVD script that set a GPRM, but this seems to get reset when the DVD is stopped. Also, from the main movie, the back button on the remote will navigate back to the 1st play media.

Any ideas ?

Sorry, this can't be done reliably. Some players remember their state when the stop button is pressed once followed by play; it takes hitting stop twice to get them to forget and act like the disk had just been inserted. Other players forget as soon as stop is pressed and act like the disk was inserted the next time you hit play.

Behavior of the previous chapter button across titles is likewise player dependent. You could try some scripting to test the situation at the beginning of your copyright clip - unfortunately, while these commands could be associated with the movie clip, you don't have that level of control in DVDA and the likelyhood is that the script commands are placed in a dummy menu (which is to say, I haven't actually looked at this level of detail in DVDA, it just seems reasonable given the way the interface was implemented), which doesn't help you at all, because it means they probably won't get executed when you need them to be.

Thanks for the advice. That saves me a lot of time trying to get it to work. I guess it could be done with something like PGCEdit, but more knowledge of the DVD structure would be needed.

1st play video is just that -- will (only) play 1st when the disc's inserted -- so at least you can get some of your desired functionality.. As Scott mentioned there's no way to do it more permanently, but if you're careful about which buttons you allow with permissions, the viewer won't see it unless they restart the DVD from full stop.

As far as DVDA & scripts go it's kind of messy in PgcEdit, with lots of dummies to hold all the possible scripting for every option, whether you've used them this project or not. It seems safer to add in DVDA, & if editing to do so by altering rather than adding to DVDA scripts. The drawback in DVDA is you can't add a script wherever you want, so might find yourself inserting dummy menu pages just to hold pre commands.
