I'm using DVD Studio Pro 4 to create a SD widescreen (letterboxed) DVD ... I've finished designing the DVD and just noticed that the DVD standard for the disc is HD DVD, instead of SD DVD, even though I had SD DVD selected in the preferences (must not have done that at the very beginning of the project?) ...

Is it possible to change the DVD standard without losing all of the work I've already done on menus and tracks?

Thanks.

AFAIK, you are SOL. If you were working in an SD DVD project, then changed it to HD DVD, DVDSP would give you a warning dialogue telling you that, if you continue, you wouldn't be able to switch it back. Which is unfortunate.

I'm not sure why it works that way, doesn't make sense to me, but it is what it is.

Thanks for the reply. That's what I thought. I was hoping for some workaround, maybe I could import the project into an SD DVD project, but that doesn't appear to be an option either.

So can I scream now?
