Vista - Media Player keeps changing my song info

I have "update track information" disabled, as well as "only add missing
information" disabled in my options menu. But Media player keeps renaming my
tracks with the wrong info, as well as contributing artists. Its getting to
be a pain because I went through almost al 5,000 songs myself and changed the
info back, manualy. But it keeps changinf it at random!!! Its starting to
really irritate me. This all started when I connected my new Archos 605 Wifi
(the Wifi has been disabled) I have Windows vista home premium.

Go to Options. On the Player uncheck the option 'add media files to library while playing'. Also it might be helpfull to prevent song information being transferred to the music library before you have edited it in your 'normal' windows map. To do this go in the Options panel to the music library tab and change/delete maps the music library automatically searches for music files.
