Why to not use the Real media support from M-Player in vlc ?
It works very well in M-Player, so that should be possible to use in vlc too ?
As for WMA-WMV, why to not use the QuickTime plug-in Flip4Mac support to have WMA-WMV support ?
It is more convenient to be able to use just one player to do everything than a different one for every format available ...
VLC has better and more complete features than M-Player or QuickTime, but it could even be better if it used what it is already existing.
