i have a mac book 10.5.8 but it says i need a snow leopard software update for imovie'11 to work . i also have a dell dimension 3000 but if i try to download just videos from my camera it doesn't work and i have heard that its so behind the times even if i did install new software it wouldn't be worth it . Any suggestions or instructions as for the best and cheapest thing to do would be hugely appreciated !
