Hm, that makes it worse :/

channels=2, samplerate=48000 sound is OK.
channels=2, samplerate=24000 sound runs at half the speed it should do.
channels=1, samplerate=48000 sound is at the right speed, but a much 
lower pitch.
channels=1, samplerate=24000 is a slow, broken, garbled mess.

In another theme, how can I specify the bitrate to use for Ogg vorbis audio?

If I use 
'#transcode{vcodec=mp4v,vb=48,aenc=vorbis,acodec=vorbis,ab=32,channels=2}:'

then I get 112kbit audio, no matter what I set the 'ab' value to.

Cheers,
Gavin.
