Playlists are not imported

[JulesG]

When importing from Winamp on my Windows 7 PC to Winamp Android on my Nexus One, the music files import correctly but the playlists do not import at all.
Winamp for Android V.0.9.2
Winamp for Windows V.5.601
Windows 7 Home Premium 64bits French
Android V.2.2 on Nexus One

Here is what I have done:

1. I manage my music with Windows Media Player where I created many dynamic playlists.
2. I converted some of those playlists to .M3U format and imported them into Winamp.
3. I then imported from Winamp (Windows) over USB to Winamp (Android).

The import process is extremely slow but it worked well except for the playlists that were not created.

Can anybody help me on this ?
