Did a scan on Gen4 and at least 8 new FAST channels appeared.I found:
Powder (about skiing) (being over 80 yrs old, this is just what I need)
Surfer (being over 80 yrs old, this is just what I need)
Skateboarding ( need I repeat myself)
Snow Boarder (being over 80 yrs old, this is just what I need)
Bike (I can still do bikes)

There are 2 Estrella channels but the font size is too small to read.
