This may be included within a 'relative' thread but the question isn't directly adressed. Or at least my search hasnt shown it to be... I am converting movies into ipod form for when mine arrives, the tech specs page shows that the ipod supports MPEG-4 format 480 by 480 pixel res compared to 320 by 240 in H.264 format. I dont really know the difference between the two, and was wondering which would give the best qualitly. Thanks in advance.
