Flash CD sound BUG

Okay, here's the sistuation - we have a Flash MX CD ROM that incorporates video running below a graphic layer, etc etc, hence the fact that it wasn't done in director.
5 months of development later, the CD-ROM works fine, except that we've discovered in testing that the sound on the videos, as well as streaming sound elsewhere in the CD, fucks up on certain computers. It gets all choppy, the entire CD slows down, and eventually you just dont' have sound working anywhere. At the same time, CPU usage drops to 5% instead of the expected 30-50%.
We have no clue why this happens, but suspect it could be because the sound quality is set to 128kbs... But if we'd rather not change that, since this is for a music group. Also, everything works just fine running from the hard drive.
If anyone out there has experienced a similar problem and knows a solution, I'd love to hear it. Many thanks

Havn't come across this one, but have you tried saving as flash5 just to see if it makes any difference?

I had a problem similar to that but it involved flash and users needing to have quicktime installed... not all users though. specifically win2000 and NT4 machines needed to have QT installed for sound to sinc perfectly... we had to wrap the flash in director and sniff for QT on NT4 and 2000... very annoying. I never realized how important director is for CD-Roms.... hope that helps a lil.

Well, there are two things - we developed the CD with Flash 6 because it has more advanced video options than director (meaning you can have vectors etc on a layer above video), so we can't put it into flash 5... Also, when we started, director didn't support Flash 6 files.
I may check for the Quicktime bug, that sounds like an interesting possibility...
Thanks

1. what OS are you having problems with or is it all?
2. how long is the video
3. what OS do you need it to run on (mac/pc/both)

i dont know everything about your project (obviously) but this might help:

basically you cant have more than 8 sounds running. So if you're not unloading your sound clips once they're done, you might get fucked.

i actually ran into this problem on a recent project for Columbia University. I couldn't find a way to stop it but I did find a work around. If the user copied the swf and all related files to the hard drive then played it from the hard drive it would work absolutely fine.
I beleiev this happened because the CD couldn't read the data as fast as Flash wanted to access it. Let me know if that helps!

Well, we also thought it might be a problem with the CD read speed, but it seems to happen sometimes from the hard drive also.
The videos aren't specifically the problem - it happens also with streaming sound elsewhere on the CD. Videos are unloaded and reloaded with a 4MB max setting using Sorenson Squeeze compression.
One thing we have noted is that it's only happened so far on computers running Win XP as their OS. Mac and other Windows are fine.
It may be a XP specific bug, but we're looking into whether it's a problem with the DirectX version...
