With software encoding, some basic commercial flagging gets done during 
the actual recording/encoding process, while a more robust flagging 
happens later.

With hardware encoding, no commercial flagging is done until after the 
recording is finished, and it take (as a rule of thumb) somewhere in 
the neighborhood of 1 - 1.5 times the length of the program to 
complete.  So if you're watching before that, your commercials won't be 

Also, if you restart mythbackend while it's flagging commercials, they 
won't ever get flagged unless you run 'mythcommflag -f'.

Finally, make sure you've got the 'Automaticall flag commercials' option 
turned on.
