Runnning two Toast valid licences simultaniously

I have two external DVD writer connected to my MacBook Pro. Note the electrical power is not provided through the USB port.

I also have two legal/valid Toast Titanium 10 valid/independent licences.

I need to be able to burn non identical videos files onto two DVD burner simultaneously. Each video file is to be creating a DVD menu from Toast Titanium.

Has anyone done that? In some occasion I could be having up three external DVD burner attached to my backbook pro at the same time.

I’ve tried in creating a T1 (toast Titanium -1) and a T2 folder with its own copy of Toast Titanium -2 application.

Thanks in advance!

I’ve found this script on the web.

However, I am not sure what it does and why it is supposed to enable to run two license of Toast simultaneously.

First reaction would be for me to execute this script twice, one for Toast A and two for Toast B.

property RDPathMac : ""

on run
	if RDPathMac is "" then
		tell application "Toast A"
			activate
			set RDPathMac to (path to application "Toast A" as text)
		end tell
	end if
	tell application "Finder"
		if not (exists RDPathMac as alias) then
			tell application "Toast A"
				activate
				set RDPathMac to (path to application "Toast A" as text)
			end tell
		end if
	end tell
	set RDPath to (POSIX path of RDPathMac) & "Contents/MacOS/Remote Desktop Connection"
	do shell script quoted form of RDPath & " &> /dev/null &"
end run

Thank you for any help!
