Confirmed: Google Home Hub works with PS Vue!!!!

The cast function in PS Vue gives the option to cast to Home Hub!!!!!

AFAIK anything that can 'cast' can do so to the Hub. It's basically a Chromecast for that purpose.

I tried that with a Hallmark Channel movie and the aspect ratio got all weird - it filled the GHH screen fully but people's faces were squished from the sides. That doesn't seem to be the case with your ABC stream above so perhaps it varies by channel. I'll do some experimenting.
