My problem is similar this post except I know my music is all in mp3 format. Basically I pointed iTunes to my Music folder and not all of it got in there. The albums I do find that haven't made it I tried to drag it to my iPod and it said (only once though) this file is not compatible with your iPod. Now, this is my first time using iTunes. I am forced because I just got a iPod touch today. Prior I had a 4g classic using Anapod (used this from 2006 until present). All songs are mp3 format, bit rate, sample rate- I'm really not anal, that's just how my library is. All files were on my classic iPod, play fine in windows. My OS is windows XP, I think I have about 200gb harddrive left, and 2 gigs of ram. I am considering moving my whole library over to my macbook since apparently the Windows version isn't so hot. Any suggestions or recommendations? I'm only posting because a google search came up empty and that error message hasn't been seen again. Thanks so much!
