It maybe a "North American" version? I know here in Canada certain versions of US channels IE F/X,MTV,Spike,OWN,etc have the US monogramming and also must contain a certain Mount of Can-Con programming. I know with OTN although it has ANT1/Sat programming it also must contain a certain amount of Canadian Contain. 
  
  
I know certain ethnic channels in Canada are like this, while other ethnic channels are the ones from that ethnic group.  
  
As for SKAI I'm not sure which it falls under?So maybe the commercials are inserted here for CRTC regulations?
