Update:

They are written correctly. We were just comparing old dumps before
Thomas integrated some fixes. However, we finally found the
problem. The codec information is not set correctly. In the track
descriptor, offsets 0x0021..23 keep this information. We found that an
MP3 track (128k/44.1) written with Sony's Hi-MD Music Transfer sets
"0x80" at 0x0023 while we wrote "0x0b". Changing this byte to "0x80"
will finally enable playback.

So, for now it's just a matter of patching a few lines of code and write
support is finally working.
