Here's a python one-liner to do this:

mythcommflag --getcutlist -f mythfile.mpg | python -c "import sys,re; 
cutlist=[re.split('\D+',l)[2:-1] for l in sys.stdin.readlines() if 
l.startswith('Cutlist:')][0]; cl=[(i+1,.04*int(l)) for i,l in 
enumerate(cutlist)]; 
cl=['CHAPTER%02d=%02d:%02d:%06.3f\nCHAPTER%02dNAME=Chapter 
%d'%(ii,int(i/3600),int((i%3600)/60),i%60,ii,ii) for ii,i in cl]; print 
'\n'.join(cl)"
