Hi Karina
Yes there's always will be a system which will cause problems.
(It's just a bit annoying though when it happens on your client's commuter)
The CD-ROM should however run even on very slow system.
>> application loads various swfs into a base swf file, and the flvs are
>> >>loaded
If you use multiple swf in your CD-ROM make sure that all swfs are initialized
before you use them. For example I once was working on a CD where loaded a swf
with a nested swf/flv player in my root swf.
After loading the swf file I sent the video url to the loaded swf file
so that the nested component in the swf could play it.
This all worked fine when I tested it on my computer and on another computer.
However it didn't work on some computers even if they had fast processors.
Eventually I found out that it was the CD-ROM drive. Some drives were just a
bit too slow. So the swf file which contained the video player component
was not loaded fast enough.
As a result the url send from the main movie did never reach the player in the
loaded swf. The solution is quite easy though. Whenever you use
multiple swf files in your CD-ROM project and you want them to communicate
between each other make sure that loaded swf file is initialized properly
before you send anything.
A bulletproof way to do this is to have interval function in your main movie
which checks the value of a variable in your loaded swf.
e.g:
// load the swf
swfHolderMc.loadMovie("someSwf.swf");
intervalId = setInterval(this, "executeCallback", 200);
function executeCallback()
{
If (swfHolderMc.getInicialized())// obviously you need a
//getInicialized function in the swf file which is loaded
{
// do something in the loaded swf
clearInterval(intervalId);
}
}
Hope this helps

However
Most of the times it is a faulty driver or some wired configuration.
I think these days it is not really necessary

Hi Karina
I have had similar problems like you.
My cd-rom in question had 2 videos (both external flvs to profit f7's
smaller memory footprint advantage over f6 regarding videos)
Both videos was rather big in pixel size and approx 3 mins length (about 30
megabytes each). So i knew they would demand a bit of 'juice'.
When testing with a 'raw' video test both a mac g4 500mhz (os9 and osx) and
a p3 600mhz (both win2k + win 98) worked fine with no performance problems
playing from a cd.
But my version with the final design was demanding quite alot more cpu to
perform well.
What i found out was that the pure presence of bitmap graphics with alpha
information was decreasing the performance (demanding more cpu) - even
though the bitmap wasn't moving or something was moving over or under it.
I still couldn't optimize it fully to fit my 'raw' tests - but it put down
the performance needs to a acceptable level.
My minimum specs ended up at mac: g4 800mhz pc: p3 800mhz (both 64mb ram)
I had other strange problems like sound issues with some pcs - some dell
configurations with sound blaster live soundcards and a certain motherboards
and cd-rom drive for some reason distorted the sound. (similar to the sound
issues with flash 5 and soundblaster pci 64 and 128) but thing like this is
out of your hands.
But well with cd-rom productions there always are some odd hw configurations
that just give problems (although in theory it shouldn't).
Using director would just giver other issues (and make the production a lot
more expensive due to the lack of cross platform projector exporting back
then). Flash gave us the unique feature to distribute video cross platform
without being dependent of 3rd party media players.
All in all the cd-rom was a success and went into its 2 edition with a total
of 70.000 units.
Cheers,
