Not in first frame!

hi,
it’s a quote of flash mx 2004 help section about attaching mc from library:

“By default, all movie clips that are exported for use with ActionScript load before the first frame of the SWF file that contains them. This can create a delay before the first frame plays. When you assign a linkage identifier to an element, you can also specify whether this content should be added before the first frame. If it isn’t added in the first frame, you must include an instance of it in some other frame of the SWF file; if you don’t, the element will not be exported to the SWF file.”

so, where can i include an instance name? i want that my attached sounds, mc’s will load in _root section. Please help me

p.s. you can find more about this in flash help, search for “attaching a movie”.
