The message you're seeing is because you've killed your backend while it 
was flagging commercials.  Running mythcommflag on the file giving the 
error would have fixed that for you. Something like "mythcommflag 
--force --file /path/to/file.nuv" should do the trick.  If it doesn't 
try searching the archives for "cutlist update".

Once you've edited the file the recorded markup table is no longer valid 
this will cause all kinds of problems.  While it's possible to get 
everything working smoothly, you'd have less hassle if you put your 
edited file into MythVideo.
