Hi there, I am new to the forum and have a question for you guys/gals. I bought my niece an iPod Touch for Christmas and I want to open it and put a movie on it for her, here fav, High School Musical of course. I have complete the MPEG4 transfer and now assume I have to sync the iPod with Itunes. Will syncing on my PC mess anything up for when she gets it Christmas and syncs it with here PC? Thanks for looking.
