The lack of an OBJECT tag may or may not be the tripwire for the problem...

the IE/Win browser can often guess to invoke a particular ActiveX Control

if you just give it an EMBED and MIME, with proper filename extension, but

there's no substitute for actually specifying which Control should render

that content.


It may also be the number of instances on the page on that computer which

could be the tripwire too... when people use multiple SWFs they usually use

a handful, rather than a few dozen, so a particular machine may have

difficulty simultaneously creating a few dozen player instances.


If the core of the problem is actually the download time, rather than

figuring which renderer to use or supporting multiple player instances,

then most browsers are set up to do four parallel downloads and they'll

stack requests after that... 24 SWF may take as long as 24 GIF in regards

to this variable. The following document has related info, even though it's

on a different subject:

"What effect does slicing have on image download speed?"

Overall, though, if someone gave you pages with 24 EMBEDs with OBJECTs,

then I'd wonder about the integrity of the rest of the page too... they

wouldn't happen to have BLINK and MARQUEE tags in there too, would they...?

;-)


(Rephrased, the pages may have additional problems, in addition to the ones

you've uncovered... please be careful that you don't get caught in a bind

between the client's expectations and what they let you actually do!)
