I once moved my entire itunes to an external hard drive?

But if it isn't music you bought from iTunes and you sync it, your music will be deleted. If it's music you did buy from iTunes, it'll be fine.

If you can get it to the music folder, windows media can now read mp4 and burn cds from mp4s that play in normal CD players (I do remember when that wasn't possible.)
