Anyone here have any experience using the CD Xtra on a multiple CD project?
We need to be able to do two things, and have had no luck under OSX
(Windows is fine (for once!)).
- We need to be able to start the program with no cd inserted, and have
the program wake up to the fact that there is one when we ask it to.
- We need to be able to change CDs at will without having the program crash.
The test program that comes with the xtra does neither of these things
under OSX on any of the machines we've tested. It either won't eject
the CD once it's been played, or it won't recognize that a new CD has
been inserted, i.e., can't get any valid data off the CD, such as
duration or number of tracks.
If we kill the instance and re-instantiate it AFTER the CD is inserted
and mounted, then and only then will it read the CD correctly. That
leaves us with two options: either put the kill/re-instantiate function
on a button for the user to click, or continually do it for them on a
timeout. I tried setting it to up to 30 seconds. There's only one
problem with either approach -- it sometimes works in Director but
crashes in the projector. If they push the button too soon, it
definitely crashes. Aarggghh.
I tried instantiating the object inside a behavior, then passing a
reference to that object to a global variable and executing calls to the
CD via the global (trying to issue CD commands directly from the
behavior either wouldn't work at all or would crash). This scheme sorta
almost worked. I could make different instances and swap them in and
out of the global reference at will, and if I ejected the CD and put in
a new one, eventually I could get it to wake up and get the new info --
but again, once I played the CD, there was no way to get it to eject, no
matter how nicely I asked the global and/or the behavior. I mean -- how
many other ways are there to say "STOP" and "EJECT"?
I've posted a test dir with varying amounts of pidgin code if anyone
wants to take a look out of the goodness of their heart. Deadline is
Monday:

happening on Macs)
Any help appreciated.
