media in pdf are sort of braindead and it's hard to get something that doesn't have side effects (attachment vs external vs ...) .. when i can't hear sound with internal files (no matter how we wrap it i cannot really test something) ... (it is tempting to just remove the code but as part of working on the interaction manual i keep it for now)
the flash dependent media are even worse ... it is supported (as usual) but not future proof
(it baffles me that the original simple movie and sound annotations are sort of gone: they delegated the rendering so no pain for acrobat and no gain in obsoleting them)
Embedded media is an illness inherited from PowerPointers. In my experience as a seminar presentation organizer, this messes-up 9 times out of 10 (unless the presenter is using his or her own laptop, and even then they cannot get it connected to the projector maybe 20% of the time...). Things are getting a bit better now on the presentation front, however. (PowerPointers still get funny font stuff from time to time). Why not, rather, depend on a link opening an external file, distributed with the pdf, letting the system figure out how this is to be done? In my experience this works more generally. Alan
