Hello there,
I found a low priority issue with v2.52 when using the numbering wizard (CTRL+K) with mp4 files. No leading zeros are entered when numbering over 10 tracks at once. It works fine with mp3 (and flac I think).
Steps for reproducing:
- Mark at least 10 mp4 files
- Press CTRL+K to start the auto-numbering wizard
- Settings: Begin at tracknumber 1, DISABLE Save total count of tracks, ENABLE Leading zeros for tracknumbers, ENABLE Reset counte rfor each directory
- Press OK
What it does: auto-numbers tracks as 1, 2, ..., 10, 11, ...
What it should do: auto-number tracks as 01, 02, ..., 10, 11, ...
Additional info: Converted wav with LameXP and Nero AAC codec from this site.
Edit: Hmm... Maybe I was too fast... does mp4 support leading zeros anyway?
Edit 2: My bad... found a thread where this "problem" was discussed before. Should have done that before -.- sorry for this and please delete 
Then I just rename the files with "%discnumber%x$ifgreater(%track%,9,%track%,0%track%). %title%" and I'm fine.
