Launch a application in the background?

Is it possible to launch a application in the background?
I have found many answers to this question but none of them work.
Is is possible that the solutions found on the web are outdated in regards to OS X 10.4

All I want is two applications to launch right away with one of them in the background.
Have the quicktime movie play and activate the hidden app when the delay is over.
What do I need to add to the following scrip to make the EMULaunch.app open in the background?

Thanks.

tell application “Finder”
activate
open document file “TGTTF_long.mov” of folder “Desktop” of folder “tim” of folder “Users” of startup disk
open application file “EMUlaunch.app” of folder “Games Folder” of folder “Applications” of startup disk

end tell
tell application “QuickTime Player”
present front movie scale screen
end tell
delay 43
tell application “EMUlaunch”
activate
end tell
tell application “QuickTime Player”
quit
end tell

Hi TIMSIT,

please try this script, I can’t verify it because I don’t have the EMUlaunch app.
You can launch applications in the background using the ignoring application responses block
The Finder tell block is not necessary.

set mov to ((path to desktop) as string) & "TGTTF_long.mov"
ignoring application responses
launch application "EMUlaunch"
end ignoring
tell application "QuickTime Player"
open file mov
present front movie scale screen
delay 43
quit
end tell
tell application "EMUlaunch" to activate
