No. You have a collection of DRM-infested files that you can't convert.

If you want to use BearShare and BearStart on Vista, right-click each program and set them up
to run in XP mode and logged in as an admin user. Seriously consider converting the computer
to XP before you get locked in permanently to the untrustworthy Vista.

Uninstall the BearFlix crippleware so it doesn't interfere anymore.

Once you get the real BearShare working instead of that v6 iMesh clone
the music you download will work on the iPod.
