This has only cropped up now in AcroReader 9.3. I'm using Acro Pro windows with XP. I have two pdf docs in a portfolio. Doc 1 has two legacy media files (wmv) and (mp3). If I use doc1 as a standalone pdf I am able to play the media file after cancelling the usual yellow media bar warning. However once I place this pdf into a portfolio along with another pdf file I no longer get the media warning bar and I am unable to play media. Have not experienced this before. Is this finger trouble on my part?
Media files will not play once pdf doc placed in portfolio format

Unfortunately not - but in truth this is first time it has happened. I am going to start from scratch on a dummy file and see if the problem arises again. Many thanks for the prompt reply.
It would be a pity if legacy media were no longer supported but I suppose it would just mean working on an older version of acrobat. We use media rich files which are distributed (in some cases archaic systems) for training. Files are kept under 5mb. Broadband has not quite made an impact as yet owing to past government regulation.
In my small experience I find that many corporates will not allow Flash installed on their IT systems which means working in Windows Media. Also many students (in South Africa) only have access to older machines in dormant setups. So while Flash would be great, bandwidth and media players are an issue. Some organisations are still using Acro 7. I may be wrong but my impression is while the latest software is evangelisied to users quite strongly, many organisations (and especially those less privelaged) using Acro Reader are still way behind. Acrobat has a presence but not really as a media document.

Playback of non-legacy multimedia in Reader 9 and Acrobat 9 uses an inbuilt copy of Flash Player - users do not need to install the standalone player or the browser plugin version, and even if they do, it won't be used.
It's impossible to close the vulnerabilities of third party media players when used to show legacy content, as Adobe of course don't have control over their code. This is why it's very strongly advised to keep it disabled - a malicious PDF can and do use the weaknesses in external media players to crash the application in a way that allows them to install viruses, keyloggers etc.
Portfolios are only supported in Reader and Acrobat 9 - below that they open as a collection or a series of attachments - so you are already generating material specific to those versions, and using Acrobat 9 native multimedia wouldn't be any more restrictive. Even if they have Acrobat 7 installed, they can co-install Reader 9 and use that to open your files.

I don't suppose you could share the problematic file with us?
