Hi, I just read that there is a pre-release of VideoLAN's VLC player available which brings decoding support for ATRAC-1 files. This is interesting for all the users who use our PythonNetMD scripts to transfer their old MD recordings to their PC. The uploaded files can be played back in VLC directly without any additional codecs. More on this can be read here: <http://www.ghacks.net/2010/04/15/test-vlc-1-1-with-gpu-acceleration/> The new version of VLC is available here: <http://download.videolan.org/pub/videolan/testing/vlc-1.1.0-pre1/> I installed VLC on my old Mac Mini G4 and successfully played some ATRAC-1 previously recorded with our scripts. Unfortunately, VLC does not play back ATRAC-3(+) yet (both WAV and OMA container formats) as opposed to ffmpeg. The VideoLAN developers were allegedly a bit reserved with integrating ffmpeg's ATRAC decoders due to the fact that these decoders were developed by means of reverse engineering. But since ATRAC-1 was developed exactly with this technique, I don't see a reason not to have ATRAC-3 support as well. Adrian
