Channels in Xfinity Instant TV....DVR upgrade?

Can Comcast provide a link to the specific channels in the Instant TV packages?   For example, the sports and news package...What specific channels are in here....ALL of them.  Not just some of them.   By locality as well.   Directing me to a channel list for regular cable packages is silly, it does not tell me

And does Instant TV include the broadcast TV fee and the RSN fees?

And is there a way to upgrade from a 20 hr DVR?   Hulu, FUBO, YouTube all over much bigger DVR storage.

I just cannot get any of these questions answered.
