I tried it again with an older build of mplayer for OSX found here
Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders
AUDIO: 48000 Hz, 2 ch, s16le, 384.0 kbit/25.00% (ratio: 48000->192000)
Selected audio codec: [ffac3] afm: ffmpeg (FFmpeg AC-3)
Indeed audio sync is a LOT better with the -demuxer lavf option :-)
It only needs a couple of seconds (around 5) when starting to get in sync
Thank you very much for the info :-)
