Anyway, I've continued my dialogue with Sky after their response and sent them the following:
Thanks for the response. It sounds like Sky have realised they should continue to show A-League matches.
I have scrolled through the sports channels on the MySky programme guide all the way to the end of Monday and still can't find Friday night's match between Adelaide and Perth, or Saturday's match between Gold Coast and Brisbane. That latter match has particular interest in NZ's football community, as it features All White Golden Boot Shane Smeltz - whose form is important for NZ's attempt to qualify for the World Cup.
Okay, you may have determined not to show those live, which is very disappointing. However, SS3 is showing 3.5 hours of news Saturday morning - ripe for delayed coverage of Adelaide v Perth I would think. And on Sunday morning, again SS3 is merely using news as a filler for four hours(!) before repeating the same A-League match from the night before, so would logically seem ripe for delayed coverage of Gold Coast v Brisbane - the missing A-League Match from the night before. If it comes to it and 4 hours of continuous news is important (!?), instead of re-showing the same A-League match, showing the second one seems to be a no-brainer.
