Here the deal I'm here at work so might as well put my pc work (haha)... Anyways I downloaded format factory to convert videos and well I noticed it has an option to convert mp3's as well. So my question is which mp4 option do I choose for my 2nd gen Ipod touch. It gives an M4A and an M4R option or will neither work? Please Register or Log in to view images I would let itunes convert but will not convert all of them. Also i do not have itunes here at work. I would like to convert them put on my portable hard drive, the take it to the house and just drag over to itunes... I've got about 20 gigs to convert.
