I'm working again in my first DVD using PD12. I have 3 questions for things I don't understand which are not in the official user guide I think.

I use the Create disc to select my 3 movies (titles) I want to add for my DVD. Since I'm burning on a standard DVD 4.7 GB I'm adding 3 videos which I know are about 1.2 GB each. So I expect they can stay in one DVD, but when I import then with HQ settings or even Smart Fit settings PD says it's too long for a DVD??? Not sure what to do!! Is it because of wrong format?

Second question: I would like to add a custom button for a short video, but this time I want a TEXT button link (not the animated thumbnail created automatically). Is this possible? I just want a textual link to the video.
I have not found answers to these questions in the user guide...

Third question: Is it possible to add a button at the end of a chapter that says "Continue". At one point in the DVD I would like it to pause (with questions on the screen) and with a button "continue" the user can decide when to resume the play. Any idea on how to achieve that?

Thank you for your help,
Andrea
