[vlc] [newb] cannot transcode

[Neal Becker]

newb here.  vlc-0.9.8a on fedora f10 (from rpmfusion).

I can play a dvd fine, but when I try to transcode I always get 
00000564] main stream output error: invalid chain
[00000565] stream_out_transcode stream out error: cannot create chain
[00000564] main stream output error: stream chain failed for `transcode{vcodec=theo,vb=800,scale=1,acodec=vorb,ab=128,channels=2} :sout-all'
[00000563] main input error: cannot start stream output instance, aborting

I've tried various transcoding options.

Any ideas?
