I have similar problems with 0.17 (I'm in Adelaide using DVB-T). End  
cutpoints end late and commercial flagging is quite spotty (using the  
"all" method of detection). The late end cut-points aren't a bug  
problem and, since commercial breaks tend to be 3 mins, I've just got  
into the habit of turning flagging off and hitting "3" "forward" to  
skip 3 mins when the commercials start.

I assume that commercial flagging is optimized for US TV and  
something in the commercial layouts on Australian free to air  
channels throws it. It seems to be especially easily fooled by the  
station's own commercials for upcoming shows that come at the end of  
ad breaks. I realise commercial flagging is a bit of a black art, so  
I'm not too surprised it doesn't work in places it probably isn't  
tuned for. I'm just happy that it works so well otherwise ;)
