the music in my ipod end up on my movies and when i go to watch them after i upload them onto my ipod ..there is no sound???....what should i do!?

huh? music in your ipod ends up on your movies? Probably the best place to ask about that is here iPod Forum, however whatever you do, don't tell them you downloaded them via LW. ;) :) It would be against their policy for you to mention it anyway.
Keep in mind there's different iPod & iTunes sections so be sure you post in the correct section. ;) :)
