Was looking at
DigitalBitRate and I see 6 "New" MPEG4 channels without names. They all have resolutions of 544x576 which is basically what a Freeview channel stream that has been crammed into a full multiplex looks like resolution-wise.
Maybe they are just load testing (though weird resolution to pick for that). Or Red Button type streams.
PID1117-1123 on multiplex C034 is what I'm referring to.
In other ponderings, notice the Project 1 and Project 2 below them. Mysterious.
Let the speculation, and maybe ultimate disappointment, begin!
