I have atv flash vs 3.4.5 do I have to use Tiger OS

I made my flash stick with version 3.4.5 which I bought on internet on official atv flash site. My Mac book pro has Leopard OS on it. Do I have to have Tiger installed in order to make the flash stick?

No you do not, 10.4 or 10.5 will work fine when making the patchstick.
