Comment 7 for bug 575798

If wished to reproduce
edit the gstreamer profile for aac to encode to Main ( aac profile=1
and encode a track

While the gstreamer profile now properly defaults to LC, previously it was set to Main, don't recollect if change occurred in Karmic or was done in lucid

Only ffplay and mplayer -ac ffaac will properly decode.

Take that same track to karmic or earlier and all players will decode including mplayer which uses internal faad decoder
