First of all, please excuse me for any mistakes in my written English, as it is not my main language. So here I go: Now that I've upgraded my ibook tangerine with a 120GB harddrive, I want to store some movies on it in a format that my ibook can handle. I will use my macbook to rip a few dvd's and convert it to the proper videoformat, but the question is, which videoformat? I suppose that my ibook can't handle divx, xvid and plain dvd's. My aim is to be able to watch some tv series on my ibook (ripped from my dvd-collection), that's all, it doesn't have to be high quality, just watchable and without, if possible, frame drops. Can anyone point me to the right direction? Thanks in advance!
