btw, for those users of relatively slow fe/be combos (I have a 1GHz  
EPIA) who haven't discovered this yet: transcoding to mpeg4 via  
"mencoder" using ffmpeg's libav codec library is *much* faster than  
xvid/divx, which is what nuvexport/transcode uses by default AFAICT.

As a data point: I was seeing conversion speeds of 1-2fps from  
"transcode" in high quality mode, while I get about 5-6fps from  
"mencoder" with analogous quality options set, plus deinterlacing and  
noise reduction. This can make the difference between an overnight  
transcode and a multi-day one on a slow box.
