Well everything (leanback & m.youtube.com) seems to work just fine for me.

But I still don't get how any of this can really benefit anyone using MicroB. I mean the original site is the easiest to use and MicroB opens that site up perfectly.

I guess I'm missing something here... Sometimes I feel that people are forcing themselves to treat Maemo as if it was Android ( = less developed in web browsing terms)
