what is the cheapest way to work with soundtracks

[OrangeDerek]

hi all,

i am using digi 002 mixer, a PC fast enough with tons of ram,err,,,,win XP Pro,
i know i can import, at least, Quicktime format movie clips into my Protools LE 6.4.1,
with a tiny screen, and composing my soundtrack for that,
but i want to know if there any cheapest way i can output that movie screen to another computer monitor,
or a 14'inch TV? i am thinking of buying any video card with a TV video output, will it do the job?
or i really need to buy those Aivd Production to just output the videio signal?

thanks
