Say you have a ts with two services, and the user is currently decoding the 
first service. If this service stops it's transmission the user (app) either 
want to exit (since it's the end of the 'stream') or switch to the other 
service (since it's not the end of the 'file'). With your interface it's 
impossible (close to) to trigger either change, since there is no notion of 
'end of substream'.
