Transcoding to theora in 0.8.6.h-4+lenny2 succeeds with MJPEG input
(actually I lose sound and it does segfault when done, but the
resulting theora video is fine).  MJPEG is the only other (non-QT)
format I have to hand.

Command and output follow:

$ vlc -vvv -I dummy test.avi --sout
'#transcode{venc=theora,aenc=vorbis,scale=0.5,channels=2}:std{access=file,mux=ogg,dst="/tmp/lowquality.ogg"}'
vlc://quit
