Yeah, first make sure your software is up to date. Second I'd recommend trying to reboot the Zune (Hold 'Back Button' + 'Up D-pad'), maybe that'll sort things out.

lukgunner is right, I made a mistake in my original description. You have to find a song on your problematic list and one that is potentially similar (using the above criteria) that is already in your library and does not sync every time you connect your device. The ZuneMediaID is binary data so its not editable by you. Also, ASF Viewer is only a tag viewing utility, no editing is possible with this program.
The screenshot looks to be an example of where you can change the format of your ID3 tags in
Mp3Tag. Since both Vista and Zune write ID3v2.3ISO-8859-1, I'd recommend using that format in rewriting your tags. You can use UTF-8 if you want, but I think the software will only see the ID3v1 tag (if that) that is written to it. Alternatively to lukgammers method of rewriting your tags by hand, and assuming you've already chosen your preferred format of writing tags. you can:
- Right click on the song
- Select "Tag copy"
- Select "Remove tag "
- Select "Tag paste"
This process works for a single file as well as selecting a list of files.
With regards to the deletion of ZuneMediaID tags, I still don't know if this works as I haven't had time to really understand the process, so far I've only been able to delete the tag from two songs (for lack of time not ability), one of which was not seen by the software before. I still haven't seen what happens if the software rebuilds the library using (will those tags be rewritten?) or if by reformatting my device and I able to bypass the problem of songs syncing repeatedly (hopefully the tags aren't rewritten upon the sync or resync process). If anyone else is experiencing these problems, by all means experiment (backup your songs and data...just in case) and post your syncing results.
