To do what you asked, you would use program.basename .  To do it right, 
you would use program.transcoded != 0 .  ;)

See, also, the example clause for "Re-record SDTV in HDTV (disable 
duplicate matching)" for the overall structure you'll need (and make 
sure you disable duplicate matching.  Note, too, that unless you get 
really fancy (a lot fancier than the example clause), it will keep 
re-recording until you delete the .mp4, so you could get 3, 4, 5... or 
more copies of it unless you notice the re-record and delete the old 
transcoded one.  You could actually handle this with a custom user job 
that runs a script that uses the Python bindings to ask the backend to 
delete the transcoded version and then enable that user job on your 
custom rule (but the specific implementation will be left as an exercise 
to the reader or someone else who feels like knocking such a script 
out--and if someone does, feel free to add it to the wiki).
