I have created pdfs with embedded mp3 audio using the legacy function (I'm using Acrobat 9.1.2 Pro). When I select the embedded audio with the files located on my computer I get the following alert which appears once when the file is first opened and allows me to select an option to add it to my trusted documents if I don't want it to appear again:

You have opened a document that contains QuickTime multimedia content/ You can decide whether to play content now and also set options for what to do when you open this document in future.
- Play the mulimedia content this one time
- Play the mulimedia content and add this document to my list of trusted documents.

So far so good.

When I burn the files to DVD-ROM and attempt to select the embedded audio from the file on the DVD-ROM, I get this alert:

You have opened a document that links to QuickTime multimedia content on a Removable medium. Please decide whether to play the content now.
- Cancel
- Play

This message has no option to get rid of it and worse still it appears every time I select an embedded audio file for playback. Hugely irritating to have to go through two processes to play back each embedded file.

If I copy the file from the DVD-ROM onto the desktop, the original alert is restored, but I'd much prefer it if the user didn't have to do this.

How do I restore the first alert above and make it work on the DVD-ROM? I would be hugely grateful for help on this as I need to go to press tomorrow! Thanks very much indeed.

You can't !

The only issue is to embed MP3 files using the AA9 new Flash tool, but it's not compatible with previous versions…

Hi Merlin,
Thanks for the reply.

I found that it was only my computer which was causing the issues with the alerts. When I played the DVD-ROM in anyone else's computer the usual (dismissable) alert came up.

I still don't understand why playing the DVD-ROM on my computer gave me the undismissable alerts, but I guess it must have to do with some of the settings in my own machine.

I'll go with the legacy embedding - it has some excellent virtues that the new Flash version doesn't.

All the best, and thanks for getting back to me,
Sheena

Hi Sheena, I'm curious, what virtues does legacy have over Flash for you?

If the web revolutionsied business and entertainment, the PDF is revolutionising "the document"

Hi,
Lots of virtues. Maybe all can be dealt with by Flash but I couldn't find a way to do it.

1. Embedding audio: we're making whiteboard displays for teaching music in primary classrooms. We have a series page design which predates the Flash version so we needed to embed the audio in the same way as before.
2. The legacy embedding enables us to format the player.
3. The legacy embedding enables us to playback both the audio and the movies in Quicktime which has some really useful features in the AV controls for teaching music.
4. I totally lost patience with trying to make the Flash version do all of the above in relation both to the audio and the movies.
5. We have to make our pdfs backwards compatible with Acrobat 6 and operating
systems which maybe can't run later versions - not entirely sure how many of those there are left.
6. If I could have found a way round embedding the audio and still using my own icons from which to select an mp3 rather than the hulking play button which Flash dropped on top of my play icon, I'd have been delighted. But I don't think that would have answered the Quicktime problem.

There were some more issues but I think those are the main ones.
All the best,
Sheena

The reason for the different style of warning is because of the way Acrobat/Flash stores your choices for trust and access - which refer to the file by name. On a removable drive it's likely someone could swap the media and open another file with the same name, but that they don't want to inherit their historical trust decision; hence it keeps asking. It does somewhat depend on how your DVD drive is categorized by the operating system (is it tagged as removable, etc.).

Yes it's true you could write over a file on your hard drive, but we can assume you'd know you did that, and be suitably wary of it. On disc or USB media you can't often tell that the file is any different, as it can have the same name, creation date, size, etc. as one you previously opened.

Many thanks, Uvsar. That answers it. Basically, I can't do anything about it; the user's settings decide how the files open. But it's good to know and if I get complaints, I'll know what to say.
All the best,
Sheena
