I was just wondering, how do you find out the model you have, im useing a classic and want to convert files i download and watch them on my Ipod. Im useing a GP3 converter, and when i go to select the correct criteria, i come to model and it just has a bunch of numbers that all follow the same type of numbers...(320x240 mpeg4) not sure if that is a measurement or what, but looking to find out the right numbers to choose.
