I have posed my problem to ComputerAudiophile and others, with no help in two weeks! I THINK I have a common problem that I can not solve. I have been ripping my CD's to a USB Hard Drive, using one PC running Windows XP and Window Media Player 11 (WMP11). I have fixed all of the meta data artwork and tracks. Works fine. At this time I have not made any playlists.
BUT when I remove the Hard Drive and carry it to my stereo rig, and plug it in to a different laptop running XP and WMP11, the tracks are a mess, most art is missing. I THINK it is a Sync issue but I can not solve it and of course Microsoft has not been any help. The tracks can be played through Windows Explorer but most of the Track #1s are missing and likely in the pile of unkown albums.
It seems ITunes is far more popular than WMP, but this seems such an easy thing to do.
