I recently had the same problem as riziko. For unrelated reasons, I need to erase my ipod and restore all of the tracks using MM. Afterwards, some of the songs were much too loud or much too soft when playing on the ipod. By browsing the files on the ipod using itunes, I noticed that the volume adjustment slider for each of these files was set to something other than zero.
Interestingly, after I fixed the volume adjustment slider in iTunes, MM would recongize these songs as being changed and would re-sync the songs to the ipod. After re-sync, the volume adjustment in itunes was screwed up again.
In about 80% of the files that had this problem, there were duplicate "year" tags (no idea how this happened). I removed the duplicates using mp3tag, and now these file sync correctly to the ipod (i.e., the volume adjustment slider is at 0). I assume that when MM syncs with an ipod, it reads the file information either from the id3 tags or the MM database and then generates the appropriate entries in the ipod database. Is it possible that MM mistakenly alters the "volume adjustment" entry in the ipod database when it encounters odd tags? I've looked at the itunesdb file, and the changes to the volume adjustment entry seem fairly deliberate (e.g., many involve changing each byte in the 4-byte word from 0x00 to something else).
I think I have fixed most of my files, but I will see if I can reproduce the above by generating a file with two "year" tags.
BTW, I'm using 2.5.4.978.
Hope this is helpful.
