The problem appears to be to do with the format of the files. The ones that don't encode have much higher bitrates, and take much much longer.

'Good' video
VIDEO: MPEG2 720x576 (aspect 3) 25.000 fps 6500.0 kbps (812.5 kbyte/s)

'Bad' video
VIDEO: MPEG2 720x576 (aspect 3) 25.000 fps 15000.0 kbps (1875.0 kbyte/s)

I found that mythtranscode has a mpeg2 to mpeg2 transcode option. I tried running this on my files first, and magically it fixed the problem.

I use a wrapper script to do my transcoding to which i added the following lines before I kick off nuvexport

# fix bad files first
store=/data/film/store
mythtranscode --mpeg2 -i $store/$file -o $store/$file.transcode.mpg
mv $store/$file $store/file.old
mv $store/$file.transcode.mpg $store/$file
