Getting VLC to transcode a WMV video

I'm trying to get VLC to transcode a video from WMV to MPEG-2 format. Here's my command and the VLC output:

vlc mms:// :sout='#transcode{vcodec=mp2v,vb=5800,width=480,height=480,acodec=mp2a,ab=128,channels=2}:std{access=file,mux=ps,url="/home/rapport.mpg"}'
VLC responds with the following:
stream_out_transcode private error: cannot find encoder ((null))
stream_out_transcode private error: cannot create audio chain
main_packetizer_error: cannot create packetizer output (wma2)
I know my syntax is simply wrong somehow, because if I use the GUI I can get the Wizard to transcode like I want.

Any help?

Transcoding with GUI

So and so the theme is transcoding, I have some problems when doing this.
Does anyone know how to transcode the video when opened with the VLC through the GUI?
This morning I transcoded a .FLV video to .AVI with ffmpeg from the command line (with the default values), but the quality 'went south' a little bit. How can I synchronise the frame size when transcoding the video, or what can I do to preserve the quality?
One more question: How can I mix-up ready made .mp3 audio with .mp4 video of one and the same size?
