so i've been browsing the web and downloading random programs to get avi's working right in quicktime and converting different files to mp3's, it's working alright but i've very little memory for what i've got on my laptop let alone what programs do what. so my question is, do any of the programs that came with my white mac book do the things i've been downloading random programs for? or is there one program that does it all that i DON'T have to buy? so far i've come across needing to convert avi to mpg, FLAC to mp3, png to JPEG, and similar. i'm learning as i go, finding out what works with my lappy and what needs to be converted to work, but my knowledge of each application is very limited. heck, i just found out that avi's work for quicktime and mpg's and m4v's for itunes. can anyone help?
