If the ipod is not listed on the left then the songs you see on the right are what is on your computer, not the ipod. iTunes does not see your iPod.
I suggest installing (or RE-installing) the latest iTunes (download it directly from the Apple website). Reboot. Open iTunes and plug the iPod into the computer. Wait a minute or two. Does iTunes now show the iPod?
OK, that worked, great! Much appreciated Allan, thanx again....
One more question, how to I transfer the video from Itunes to my Ipod? I tried transfer, but nothing shows up in the video menu of my ipod....
