Perhaps you have a point when it's coming to your point about different encodings on the mp3 files. Some I've downloaded (Legally) from different sources and some were cut and edited with an mp3 editor. Though all have the .mp3 file extension, like you said, the may have been encoded differently.
I previously suggested Windows 7 instead of Windows XP. (I never had your problem on Windows 7.)
Another idea popped up today ... have you considered that you might have a bad USB port or corroded or bad USB socket? Perhaps just using a different port or USB cable will make your problem magically disappear.
