@Safranente: Your problem should be fixed with a new version. I have it ready for release, but right now the upload to the components page is not working...
"H:\Install Files\qaac\qaac.exe" %in% --raw --raw-rate %sr% -V 63 --ignorelength -o %out%

You're welcome! Onewaysync will automatically transfer tags from the source to the resulting m4a, so that album art is only embedded in the m4a if it was already present in the source file. The other method is to use folder based album art, e.g. folder.jpg.
Would it be possible to have a setting per task on whether to create a playlist file for that task?
