Ive had limewire for a while now and everythings fine on the songs front but when i come to downloading videos i have some problems. I have an ipod video so i have to download mp4s and ive been doing this fine, ive downloaded about 10 videos but only about 5 of them work. Some play on itunes and others dont so i try to play the through quicktime and it says this is not a movie file. so why do only some of the mp4s play through itunes? ive checked properties and compared a video that does and doesnt work and they are exactly the same someone please help me
