There is no easy way AFAIK. I am trying todo the same thing and what I 
currently do is:
  1) Add the commercial cutlist to to cutlist
  2) Nuvexport nuv+sql
  3) Cut the thing by hand in avidemux using the extracted cutlist
  4) rebuild the mpeg file (== the nuv file)
  5) Update the sql with a new index
  6) import the nuv+sql into myth


This is a drag, even though parts of the above runs through scripts already.
I am still experimenting with parts of the above, but I am doubtfull if
full automation is possible this way. Part of the difficulty is that avidemux
relies heavily on the gui and the gui can't be turned off.
