I'm using a Sky Stream puck.
When I switch it on I'm present with a consolidated view of everything from all sources, but there's a header menau of sorts that allows me to select Movies, Series, News, Sport etc. If I open Sport I can then choose a specific type of sport (F1, football etc) at the top or scroll down through what appears to be a mish-mash of everything.
AFAIK there's no mention of what channel the various content options are coming from but maybe I'm just not paying enough attention.
I have to say, I like to consider myself a pretty tech-savvy guy but this is making me feel old & confused.
