Yeah, though I'm trying to avoid having to encode everything twice - for
reasons of quality and of execution time. Still, I may go that route anyway
in the hope of using Avisynth in the final stage for a little further
processing (well, fading of cuts).

Having pared back my command-line to the basics, though the errors are the
same, mencoder gets through the first cut (which starts at the first frame),
then the first clip, then at the next cut starts to output lots of errors
along the lines of...

"Too many video packets in the buffer: (4096 in 8256489 bytes).
Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.
Broken frame at 0xD9AA2"

The command-line options were...

mencoder.exe -edl tmp.edl -o tmp.avi tmp.mpeg -hr-edl-seek -oac mp3lame
-lameopts mode=2:cbr:br=192 -ffourcc XVID -ovc lavc -lavcopts
vcodec=mpeg4:vbitrate=1200

And the initial mencoder output was (apologies for length)...
